研究課題

表面の異方性を活用した配位アシンメトリーの構築

研究組織

研究協力者:邨次 智(名古屋大学大学院理学研究科・助教)

研究内容

酸化物やカーボンなどの固体材料の表面を異方性を有する巨大配位子とみなし、固体表面に存在する各種官能基と金属錯体の一部を反応させる金属錯体固定化法を金属中心により高次の非対称配位圏を導入する手法として用い、表面・界面を介した金属配位アシンメトリーを創出することを目指す。例えば、キラル金属錯体や集合体を固体表面に固定化し、巨大配位子である表面の異方性によって、空間的にさらに制約された非対称配位圏を有する金属中心を構築し、その構造・挙動・触媒機能を明らかにする。また、プロキラル金属錯体やラセミ混合物の金属錯体を固体表面に固定化し、より高次の非対称配位圏を表面で構築することを目指す。

専門分野

錯体化学、触媒化学、X線分光学、表面科学

研究キーワード

固定化錯体、固体表面、触媒、表面キラリティー
