研究内容

本研究は、金属元素を立体制御、反応場、物性発現の場と捉え、従来未開拓であった金属錯体における非対称配位圏の設計・合成と異方集積化法を理論・実験・計測により開拓することを目的とし、配位結合の分子レベル制御に基づき、金属錯体およびその集積体、空間構造、電子状態の非対称性・キラリティー構築により、新しい学理「配位アシンメトリー」を創出する。これに基づき、キラル金属錯体の構築、プロキラル金属錯体の不斉誘起、キラル集積のための新手法を確立し、高い異方性や指向性を有する新機能分子・材料へ展開する。

専門分野

錯体化学、超分子化学、生物無機化学

研究キーワード

配位アシンメトリー、金属中心キラリティー、不斉誘導、非対称自己集積、キラル空間
