Research Abstract

配位子のアルキル鎖を伸ばすことによる鎖間相関の調節、更なる多核化(三核)、或いはキャリヤードーピングによるバンドフィリング制御等により、物質探索・物性探索を行った。低温構造解析により、格子歪みに関する情報を得た。誘電率測定は電荷秩序転移に関する有力な知見を得ることが出来るため、広範囲な周波数特性を調べた。低周波ラマン分光、赤外・遠赤外分光などにより、電荷・格子結合の状態を調べた。また、白金のNMR、メスバウアー分光、ESRなどの測定により、スピン・電荷結合に関する知見を得た。架橋配位子を省いたダイレクトチェイン型錯体の合成も行い、伝導性、電荷秩序状態を詳細に調べた。
