Outline of Final Research Achievements

We aimed to develop a new compound whose polarization can be controlled through thermal- and light-induced metal to metal charge transfer in a CN bridged complex. We developed an iron-cobalt trinuclear complex having a V-shaped structure, {[Fe(Tp)(CN)3]2Co(dpa)2}2H2O (Tp = hydridotris (pyrazol-1-yl) borate, dpa = 2,2'-dipyridylamine). The trinuclear complex exhibits the switching in magnetic property and dipole moment through a metal to metal charge transfer between Fe and Co.

Academic Significance and Societal Importance of the Research Achievements

メモリー、センサー、波長変換材料などへの応用を目指して、極性構造を有する物質の開発が盛んに行われている。特に、分極特性をスイッチできる物質は強誘電メモリー材料や焦電センサーとして広く利用されている。本研究では電子移動に基づき磁性、及び双極子モーメントが変化する三核錯体を開発した。分子配向制御技術と組み合わせることで新しい分子デバイスへ発展できる可能性がある。
