Abstract Four trans-heteroleptic paddlewheel-type diruthenium(II,II) compounds [Ru2(RCO2)2(2,6-(CF3)2ArCO2)2(THF)2] were synthesized using 4 types of polycyclic aromatic hydrocarbon (PAH) carboxylate RCO2− together with 2,6-bis(trifluoromethyl)benzoate (2,6-(CF3)2ArCO2−) and tetrahydrofuran (THF) as axial capping ligands. The redox potential (E1/2) for [Ru2II,II]/[Ru2II,III]+ was observed in the range of 48 to 116 mV, and the HOMO energy level calculated based on the atomic coordinates of the solid-state structure was found in the narrow range of −4.31 to −4.42 eV, which was hardly affected by the PAHs introduced.

Abstract We compare the calculated spin structures of magnetic metal-organic frameworks consisting of paddlewheel-type diruthenium complexes and tetracyano-p-quinodimethane derivatives using density functional theory calculations with Gaussian basis sets and DFT + U/plane-wave calculations under periodic conditions. The calculated results indicate that the asymmetricity of the spin density inside the [Ru2] unit disappears in the periodic systems. In addition, based on the partial spin density analysis, the electron conductivity would be switchable by changing the spin states of the metal-organic frameworks.

Although a widely used and important industrial chemical, carbon disulfide (CS2) also poses a number of hazards due to its volatility and toxicity. As such, the development of multifunctional materials for the selective capture and easy recognition of CS2 is one of the crucial issues. Herein, we demonstrate completely selective CS2 adsorption among trials involving H2O, alcohols, volatile organic compounds (including thiol derivatives), N2, H2, O2, CH4, CO, NO, and CO2. We also showcase its fine detection using remarkable luminescent response in an Au(I)‐based metal−organic framework (MOF) of {ZnII(pz)[AuI(CN)2]2} (pz = pyrazine; 1) with a two‐fold interpenetration network. Ex situ single crystal X‐ray diffraction for 1 and CS2 accommodated 1 suggested that the Au···Au atoms are not only luminescent centers but also act as interaction sites for CS2 modulating the Au···Au contacts. These experiments revealed the specificity of CS2 and how changes in the CS2‐induced structure. Based on the obtained structural formation, 1 exhibited a sensitive detecting ability for CS2 with an ultrafast response time of less than 10 s. Ex situ time‐resolved photoluminescence analyses developed in this work implied that CS2 varied the energetic relaxation at the excited states related to the luminescent efficiency of the resultant MOF system.

The paddlewheel‐type dimetal core ([M2]) is a ubiquitous motif in the nodes in coordination polymers (CPs) and metal–organic frameworks (MOFs). However, their preparation has relied on ligand‐substitution‐labile metal ions owing to challenges associated with crystallization. Consequently, examples featuring ligand‐substitution‐inert metal ions, such as Ru or Rh, are scarce. This study presents the synthesis of novel reticular imine‐linked CPs incorporating the paddlewheel‐type diruthenium(II, II) ([Ru2II,II]; 1‐Ru) or dirhodium(II, II) ([Rh2II,II]; 1‐Rh) subunits. The synthetic approach involved a Schiff base dehydration condensation reaction between p‐formylbenzoate‐bridged [Ru2II,II] or [Rh2II,II] precursors (i.e., CHO–Ru and CHO–Rh, respectively) and 2,5‐dimethyl‐1,4‐phenylenediamine in a 1:2 ratio. The catalytic activities of 1‐Ru and 1‐Rh for the photochemical reduction of CO2 in a heterogeneous system depended on the metal site. The 1‐Rusystem exhibited exceptional selectivity, generating 3.0 ´ 104 mmol g‐1 of CO after 24 h of irradiation, whereas the 1‐Rhsystem generated a lower amount of CO (3.2 ´ 103 mmol g‐1). The catalytic activity of 1‐Ru ranked with that of all relevant catalytic systems. This study paves the way for the exploration of [Ru2II,II]‐ or [Rh2II,II]‐based polymers with open metal site‐dependent functional properties.

The high surface area, open pore‐structure and atomic‐level organization inherent in many covalent organic frameworks (COFs) make them an attractive polymer platform for developing functional materials. Herein, a chemically robust 2D COF (TpOMe‐DAPQ COF) containing phenanthraquinone moieties was prepared by condensing 2,4,6‐trimethoxy‐1,3,5‐benzenetricarbaldehyde (TpOMe) and 2,7‐diamino‐9,10‐phenanthraquinone (DAPQ) using the convenient mechanochemical method. The poor charge‐storage capacity of the pristine TpOMe‐DAPQ COF was substantially improved by first investigating its redox‐site accessibility (RSA) using different conductivity‐enhancement methods, and then optimizing the amount of EDOT needed to perform an in‐situ polymerization. The resulting composite (0.4EDOT@TpOMe‐DAPQ) was characterized and its enhanced charge‐storage capabilities enabled it to be used as an anode material in an aqueous Mn beaker‐cell battery capable of delivering 0.76 V. This work outlines the rational design approach used to develop a functional charge‐storage material utilizing a COF‐based polymerization platform.

Abstract Partial charge fluctuations in the charge‐ordered state of a material, often triggered by structural disorders and/or defects, can significantly alter its physical characteristics, such as magnetic long‐range ordering. However, it is difficult to post‐chemically fix such accidental partial fluctuations to reconstruct a uniform charge‐ordered state. Herein, we report CO₂‐aided charge ordering demonstrated in a CO₂‐post‐captured layered magnet, [{Ru₂(o‐ClPhCO₂)₄}₂{TCNQ(OMe)₂}] ⋅ CO₂ (1⊃CO₂; o‐ClPhCO₂⁻=ortho‐chlorobenzoate; TNCQ(OMe)₂=2,5‐dimethoxy‐7,7,8,8‐tetracyanoquinodimethane). Pristine porous layered magnet 1 had a partially charge‐fluctuated ordered state, which provided ferrimagnetic ordering at T_C=65 K. Upon loading CO₂, 1 adsorbed one mole of CO₂, forming 1⊃CO₂, and raising T_C to 100 K. This was because of the vanishing charge fluctuations without significantly changing the framework structure. This research illustrates the post‐accessible host–guest chemistry delicately combined with charge, spin, and lattice ordering in a spongy magnet. Furthermore, it highlights how this innovative approach opens up new possibilities for technology and nanoscale magnetism manipulation.

Abstract Electron donor–acceptor (DA)‐type metal–organic frameworks (MOFs) with valence instability are promising molecular materials for the design of photo‐responsive and electronic/magnetic functional materials. Here, ultrafast photoinduced dynamics in a DA‐type layered MOF that exhibits a charge‐transfer (CT)‐type phase transition are reported: (NPr₄)₂[Fe₂(Cl₂An)₃], where NPr₄⁺ = tetra‐n‐propylammonium and Cl₂An²⁻ = 2,5‐dichloro‐3,6‐dihydroxo‐1,4‐benzoquinonate. At room temperature (300 K: RT), ultrafast photoinduced CT between the Fe and Cl₂An ions induces a sensitive change in the state associated with the valence instability from a single‐chain, electron‐correlated state to a new photoinduced, structurally modulated state. In the photoinduced state, two absorption bands are observed, one on the higher‐energy side of the CT band and the other in the mid‐IR range. This strongly implies that the local inversion center on the Cl₂An ion that exists in the initial state disappears instantly upon photoexcitation, causing an ultrafast change in the lattice structure due to the softening of rigid bonds. This has never been realized in thermal excitation. These findings demonstrate that a new electronic state with a unique lattice structure—i.e., a photoinduced hidden state—appears in this MOF system at ultra‐high speed (within 110 fs) upon photoexcitation at RT.

本挑戦的研究では、「特定のゲスト分子に対して電気的・磁気的信号を発信するゲスト応答型多孔性分子材料」の開発を目指し、酸化還元活性なゲスト分子に対してホスト-ゲスト間電子移動を起こす多孔性分子格子を創製することを目的としている。電荷移動型の錯体格子としては、これまで当研究室で研究展開されてきた水車型のルテニウム二核(II,II)錯体（電子ドナー；D）とTCNQ誘導体（電子アクセプター；A）からなるD2A型二次元層状材料をターゲットとする。本年度は、TCNQ-を有する一電子移動型またはTCNQ2-を有する二電子移動型のD2A-MOFにおける、ヨウ素挿入によるTCNQn-のホスト-ゲスト間電子移動誘発を計画した。その結果、新たな一電子移動型D2A-MOF（ゲストフリー体はTN = 84 Kの反強磁性体）を開発し、ヨウ素を反応させることにより、常磁性体に変換する磁気相変換を見出した。本系は、加熱脱気することにより元のゲストフリー体に戻る（磁気相スイッチング）。その場測定を含めた詳細な検討により、細孔内で2(TCNQ-)+3I2 →2TCNQ + 2I3-の反応が起こっていることが確認された。これは、ホストーゲスト間電子移動により磁気相変換を実現した初めての例である。

It is very difficult to separate each other two kinds of molecules with their similar sizes and boiling points such as nitrogen (N2) and oxygen (O2) molecules even in a common way. In this project, we aimed two research directions of i) distinguishing these molecules using their magnetic characteristics, e.g., diamagnetic for N2 and paramagnetic for O2, and ii) developing porous magnetic materials that discriminate adsorption properties of these guest molecules. In conclusion, we found two types of new porous magnets: a layered ferrimagnet magnetically distinguishes O2 molecules and a layered antiferromagnet changes its magnetic properties depending on guest molecules of O2, N2, and CO2.

The research project aimed to design molecular lattice compounds that undergo drastic changes of their physical properties such as electronic conductivity and magnetism due to the influence of chemical stimuli. The chemical stimuli were assumed as insertion/extraction of guest molecules such as solvent molecules and ubiquitous gas molecules, for which porous conductive magnets with lattice frameworks were rationally established based on the previous studies. Focusing on lattices that undergo the dynamical change of charge ordered state derived by a small modulation of structures, charge-flexible lattices were, in particular, synthesized by tuning HOMO/LUMO energy levels of electron-donor/-acceptor building units. Consequently, some characteristic materials such as magnetic sponges undergoing electronic modulations or porous magnets distinguishing electron spins of oxygen molecules were established.

研究課題III：「 D’[{Ru2}2TCNQ] (D’ = [Fe(Cp*)2]+誘導体)の開発と物性制御」について現在までにπ型ピラーとして用いた[FeCp*2]フェロセン誘導体については、現在までに多様な誘導体が合成されており、多くの情報がある。そこで、TCNQRxとの電荷移動・電子移動を考慮しつつ、本系に組み込むことを行う。これにより、エネルギーレベルを調整できることと同時に、TCNQRxとのπスタック様式が僅かに変わり、磁気的な相互作用を制御できると期待される。本研究では二次元磁気層の構築素子としてベンゾエイト二置換体架橋のPaddlewheel型Ru二核錯体である[Ru2(CF3CO2)2(2,6-CF3PhCO2)2(THF)2]を原料として用い、[Ru2]の嵩高さを調整することで空孔を確保し、より層間にカチオン種が存在しやすい環境を作ることを試みた。この指針の元に合成を行った結果、テトラブチルアンモニウムのような無機カチオンからクラウンエーテルに含有された金属カチオンまで、幅広い種類のカチオンを磁気層内に内包する化合物の合成が可能であることを明らかとした。研究課題IV：「多孔性π-PLF構造を用いた分子吸脱着とホスト・ゲスト相互作用を利用した物性制御」についてこれまで合成したπ-PLF構造は比較的安定であり、空隙に存在する溶媒分子を除いてもその細孔を残したままPLF構造を保持する。そのため、ガス吸着特性を測定し、同時にin situでの磁気測定の検討に入った。本測定は今後も継続とするが、ガス吸着により磁気転移の変化する物質や変化しない物質などの多様な化合物が得られており、非常に面白い成果を挙げている。

Three types of multi-dimensional molecular network compounds, (i) a mixed-valence one-dimensional magnetic chain, (ii) an electron-donor/-acceptor alternating chain undergoing temperature-induced neutral-ionic phase transition, and (iii) a three-dimensional network compound undergoing quasi-Spin-Peierls transition, were investigated from the viewpoint of multiferroics that induces synergistic phenomena coupling magnetic spin ordering and electro-dipole ordering. We unfortunately could not find any data clearly indicate a multiferroic phenomenon, but succeeded in capturing a transition coupling between charge-ordering and structural phase transition by variations of dielectric signals.

The doping of a redox-inert (insulator) dopant (P) into a D+A－ chain in place of neutral D enables the creation of mixed valency A0/A－ domains between P units: P-(D+A－)nA-P, where n is directly dependent on the dopant ratio, and charge transfer through the P units leads to electron transport along the framework. This hypothesis was experimentally demonstrated in an ionic DA chain synthesized from a redox-active paddlewheel [Ru2II,II] complex and TCNQ derivative by doping with a redox-inert [Rh2II,II] complex.

The aim of the research project is to establish multi-functional molecular materials using electron-donor/-acceptor-based conductive molecular magnets or highly redox-active molecular framework compounds, in which not only ‘physical responses’ such as magnetic ordering, electron transporting, and dielectric responses resulted from their frameworks, but also ‘chemical reactions’ involving chemical adsorption/desorption of gaseous molecules in nano-sized pores are synergistically functioned. We discovered tunable selective NO adsorption behavior in a series of electron-donor-type chain compounds based on paddlewheel-type diruthenium(II, II) complexes, and succeeded to capture modifications involving gas adsorptions as gate-opening gas adsorption transitions and chemical interactions caused by host-guest interactions as electric signals by applying ac electric fields in situ gas handling.

D/A集積体を基にした磁性・伝導性・誘電応答の“外部摂動”制御に関する研究について、以下の課題iii)ーv)について検討した。課題iii）二次元層状化合物[{Ru2(CF3CO2)4}2(TCNQ)]・2(anthracene)・n(solvent)の脱溶媒による格子内アントラセン分子異動のダイナミクスに関する研究を展開した。この化合物は、溶媒が脱離することで、結晶ー結晶転移を起こし、脱溶媒化合物に変化する。その時、層間に挟まれたアントラセン分子は、脱離した溶媒のスペースを埋めるように、約４０％の分子が結晶内を移動する。この移動ダイナミクスを粉末X線回折で捉える実験を行った。また、二次元層状化合物の他に、アントラセンが挿入されたラダー型の化合物を作ることにも成功し、その溶媒脱離に関する研究も行った。多孔性配位高分子が注目を集めているが、自然界は真空空孔を嫌う。そのため、もし結晶内に移動可能な分子があった場合、細孔を埋めるように安定化を図るのかもしれない。このような系は非常に珍しく、極めて重要な知見を与える。課題iv）本系で扱うD/A系の幾つかは、高電場をかけることにより非線形伝導を示す。この非線形伝導状態の外部磁場依存性について検討を行った。課題v）本系で扱う化合物は、溶媒脱離などにより構造を保持したまま結晶ー結晶転移を起こすが、同時に、生じた結晶中のスペースを利用した置換基のフリップ運動が見られる場合がある。特にこのような系について、溶媒和状態（OFF）と脱溶媒状態（ON）で置換基のフリップ運動から誘起される電場応答について測定を開始した。外場として溶媒脱着や選択的な分子（ガス分子など）の吸脱着を利用して、その効果を電気信号でアウトプットする系は、今後多孔性分子材料の研究では極めて重要になってくる。分子の吸脱着を直接観測するのはなく、微小系利用による、高感度、即応的な電気信号をどのように得るべきかが今後の課題である。

Our purposes of this project are to create the new physical properties and functionalities in superparamagnets by switched with the external stimulus. One strategy that we have employed is to prepare conducting SMMs, like [Pc_2Tb]Cl_0.6, which has a blocking temperature of 47K and whose magnetic properties showed hysteresis below 10K. This SMM shows negative magnetoresistance below 8 K. In our second strategy, we have incorporated planar memory into a double-decker Tb(III) SMM (Pc_2Tb). In addition, we have observed a Kondo Effect at 4.8 K by using scanning tunneling spectroscopy (STS) for the first time. We can control the appearance and disappearance of the Kondo peak by injecting an electron using an STS. This is considered to be the first single-molecule memory device. In our third strategy, we have prepared field effect transistor (FET) devices of SMMs. The Pc2Dy device shows ambipolar (n- and p-type) behavior, whereas the Pc2Tb device shows p-type behavior. This difference is explained by the energy levels of the lanthanide ions. In the fourth strategy, we have doped Cs atoms onto Pc_2Y. Although Pc_2Y molecules show Kondo peaks due to the unpaired spin in the Pc ligand, when doped, Kondo peaks are not observed due to coupling of the radical Pc and the 6s electrons of the Cs atom. Finally, by doping with and manipulating the Cs atoms, we could write the letters T and U, which are the initials of Tohoku University.

Metal-organic frameworks(MOFs) comprised of electron-donors(D) and. acceptors(A), i. e. D/A-MOFs, are intriguing candidates toward magnetic, conducting, and their synergistic materials, because the charge transfer(CT) of D^0A^0→D^<.+> A<.-> in MOFs is not only involves an electron transfer from D to A, but also generates a new spin set of S=1/2 spins with an exchange interaction. The D : A=2 : 1(or 1 : 2) system, which allows to construct multi-dimensional MOFs as ladder, 2D, and 3D networks, is the most fascinating target because this formula can possibly create a mixed-valence network system with one-electron transfer. Covalent-bonded assemblies of paddlewheel diruthenium(II, II) complexes[ Ru_2^<II, II>] and TCNQ/DCNQI demonstrate such materials, in which both magnetic and conducting properties are tuned by intra-lattice CTs.

AF相/磁化緩和を示す化合物群の開発 Mn_2Ni系単一次元鎖磁石は、Mn^<III>-Ni^<II>-Mn^<III>S=3三核ユニットが強磁性的に配列した擬Ising鎖であり、[Mn^<III>_2(5-MeOsaltmen)_2Ni(pao)_2(phen)]PF_6において鎖間相互作用により反強磁性的相転移を起こすにもかかわらずT_N以下の温度で遅い磁化緩和を示す新しい磁石相を発見した。この知見から、Mn:Ni=1:1型の単一次元鎖磁石について、BPh_4^-のような大きなカウンターイオンを持つ単一次元鎖磁石(カウンターイオンが鎖間を隔離する)と、比較的小さなカウンターイオンであるPF_6^-を持つ同様な一次元骨格を有するフェリ磁性鎖を得ることに成功し、後者が、反強磁性体にもかかわらずT_N以下の温度で遅い磁化緩和を示す新しい磁石相であることを見出した。このMnNi系は強い鎖内相関を持つ単一次元鎖磁石(Glauberダイナミクスで解釈できない)であるため、このように鎖内、鎖間ともに強い相互作用系でもこのような単一次元鎖磁石を基にした反強磁性相ができることが明らかとなった。しかし、鎖間相互作用が十分に強い系では、緩和は見られない。同様に、MnNi系よりもさらに鎖内相関の強いMnCu系でも反強磁性相の発見に至った。これらの単結晶による磁化緩和の解明までは本年度で行うことはできなかったが、今後、単結晶を用いた磁場下での磁化緩和挙動を調べることにより、この新しい磁石相の理論的な解明に繋げたい。

「Single-Molecule Magnet (SMM)を交換相互作用で一次元に連結するとSingle-Chain Magnet (SCM)ができる」という本研究者が提唱した極めて単純な方法論を基に、SMMとなるMn(III)二核錯体、それを水素結合の弱い相互作用で一次元化した化合物、反磁性金属で連結した反強磁性SCMを合理的に合成し、極めて弱い摂動としての鎖内相互作用から相関に至る過程での磁化緩和ダイナミクスを追跡することに成功した。また、SMMとなる[Mn^<III>-M^<II>-Mn^<III>](M^<II>=Ni^<II>,S_T=3;Cu^<II>,S_T=7/2)を設計し、これらSMMを強磁性相互作用により一次元に連結することにより、一次元相関(regular chain又はdimerized chain)に依存した磁化緩和を理論的に説明することに成功した。これらの例は、鎖内相互作用(又は相関)のSCM挙動への影響を系統的に示した例である。空間としての一次元鎖は、鎖間相互作用として影響を受けるはずである。その相互作用が強く、鎖間相関を作る場合は、バルク磁石挙動を示す。実際に、同様な構造の一次元鎖で、鎖間環境を変えることでバルク磁石とSCMの作り分けにも成功している。しかし、実は、鎖内相関が鎖間相関よりも十分に大きい場合には、三次元的な長距離秩序を起こした後でも鎖内の磁化反転は起こりうることがわかってきた。

Quasi-one-dimensional halogen-bridged Pd compounds take a Pd(II)-Pd(IV) mixed-valence state or charge-density-wave state or Peierls Insulator due to the electron-phonon interaction. In order to realize a Pd(III) Mott-Insulator we used the sulphonic acid counter anions with long alkyl chains. In the raw of the five alkyl chain, the Pd compound shows the phase transition from the Pd(II)-Pd(IV) Peierls Insulator into the Pd(III) Mott-Insulator about 200K with hysteresis, which is the inverse Peierls transition. This phenomena were evidenced by ESR, X-ray single-crystal analyses, single-crystal reflection spectra, electrical conductivities, etc. In the case of the ten and twelve alkyl chains, the Pd(III) Mott-insulators are the ground state even in mom temperature, which is the first example. These interesting phenomena are well explained by the fastener effect or chemical pressure of the long alkyl chains. In the Pd(III) Mott-Insulator at 15 K the photo-irradiation with the energy of the charge transfer band (0.5eV) produced the Pd(II)-Pd(IV) Peierls Insulator state, while the photo-irradiation with L5 eV produced the metallic state. Such photo-induced phase transitions occurred in femto-seconds, which are available for the ultra-fast optical communication.

強磁性型単一次元鎖磁石[Mn^<III>_2(saltmen)_2Ni^<II>(pao)_2(L^1)_2](A)_2 (L^1=monodentate ligand such as pyridine, A^-=counter monoanion)は、-NO-を介して反強磁性的にカップリング(J【approximately equal】-20K)した[Mn^<III>-Ni^<II>-Mn^<III>]ユニットがS=3の一軸異方性スピンユニットを誘導し、このユニットがbi-phenolate架橋(-(O_<Ph>)_2-)を介して弱く強磁性的に相互作用(J'【approximately equal】+0.7K)した、J'の相関により解釈される磁化緩和ダイナミクスを発現する(磁化反転エネルギー障壁:L>>ξの時Δ_<SCM1>=8J'S^2+|D|S^2;L≦ξの時Δ_<SCM2>=4J'S^2+|D|S^2。Δ_<SCM>とΔ_<SCM2>は相関長効果)。即ち、ただ一つのJ'により相関される一次元磁性鎖である。しかし、[Mn^<III>_2(5-MeOsaltmen)_2Ni^<II>(pao)_2(bpy)](PF_6)_2は、構造的に上記の単一次元鎖磁石と極めて類似しているが、二種類のMn^<III>-(O_<Ph>)_2-Mn^<III>架橋環境を持つため、J'はJ_1'とJ_2'の二種類存在し、交互一次元鎖を形成している。Mn^<III>周りの配位構造(配位空間)は、両者で非常に似ているが、磁気的な相関長は、わずか2ユニット分(n=2)しかなく、おおよそJ_2'〜0であり、J_1'の相互作用のみ有効なS=3二量体(即ち、n=2の単分子磁石)として振る舞うことが明らかとなった。このとき、もはや磁気的な相関は磁化緩和には関係なく、Δ_<CF>=n|D|S^2の単分子磁石挙動のようになると考えられる。相関の有無については、HF-ESR(High-frequency and high-field ESR)の結果も支持している。この僅かな構造(配位空間)の違い([Mn_2(saltmen)_2]と[Mn_2(5-MeOsaltmen)_2]の架橋構造、及び同様な[Mn_2(5-MeOsaltmen)_2]の二量体構造における磁気的な違い)が単一次元鎖磁石の磁化ダイナミクスに大きく影響を与えていることが明らかとなったばかりでなく、相関の原始n=2の単分子磁石とn【approximately equal】100の単一次元鎖磁石の違いを明確に示すことに成功した。

本年度は、単一次元鎖磁石の磁化緩和現象の解明に向けたHF-EPR測定と、相関に関する磁気構造の視点からの解明を目指してMn(III)二量体の研究を行ってきた。まず、単一次元鎖磁石[Mn_2(saltmen)_2Ni(pao)_2(py)_2](ClO_4)_2のHF-EPRは、孤立系に見られない、温度変化によるシグナルの磁場移動が観測され、単一次元鎖磁石の磁化緩和が相関に密接に関わっていることを証明した。また、その解析により、1.5Kでの低温では、Glauberダイナミクスに関する磁化緩和でなく、磁区によるspin wave磁化緩和による可能性が示唆された。これは、高温部で相関長が有限鎖長よりも短いときにはGlauber機構が優勢で、低温部で相関長が有限鎖長に達し、磁壁による核化が起こると一次元磁区のspin wave機構が優勢になることを示している。このような機構の変換が真に起こっているかは、今後の詳細な検討が必要であるが、少なくとも、極低温部では、磁壁による核化は他の測定からも支持されている。次に、上記の単一次元鎖磁石の相関の強さと磁化緩和の関係を調べるため、[Mn2(5-Rsaltmen)2(L)2](A)2の二量体化合物について、RとLの配位子の違い及び対イオンA^-の違いがMn…Mn間の磁気的相互作用にどのように影響するかを調べた。RとL及びA-の違いにより、21種類の二量体を系統的に合成し、構造と磁性を明らかにした。その結果、R=H,Clの時は、Mn…Mn間の強磁性的相互作用の大きさは架橋構造Mn-O*距離に比例するのに対し、R=Br,MeOはMn-O*距離の僅かな違いでも劇的に相互作用の大きさに敏感であることが明らかになった。

Electron transfer complexes based on porphyrinatomanganes(II) and cyano-acceptor molecules show bulk ferromagnetism. The characteristics of these complexes are : (1)high critical temperature, (2)well designed crystal structures, and (3)high cohesive forces. However, the detailed mechanism of this magnet, especially, the relationship between the magnetism and the three-dimensional structure, is still unclear, With an aim obtaining the relationship and future understandings, we designed the tower shaped supramolecular alley. To obtain such materials, structurally well defined porphyrin oligomers are required. The oligomers were prepared by the coupking reaction of Suzuki porphyrin, boronic acid substituted porphyrin, and halogenated porphyrins. The well estimated reaction condition afforded the oligomers in 80 to 95 % yield. The resultant oligomers were metallated with Mn(OAc)_2 to give the corresponding Mn(III) complexes. The Mn(II) complexes were obtained by the reduction reaction using NaBH_4. We are currently estimating the magnetic properties of the complexes.
