研究内容

本新学術領域研究では、多彩なアキラル無機ナノ結晶を集積したアシンメトリーナノ結晶構造体を構築し、構造に特有のアシンメトリー化学を展開する。具体的には、以下の項目を検討する(図)。(1)ヘリカルキラリティー原子配列をもつキラル金属クラスターを合成し、不斉触媒能やキラル磁性の探索を行う。(2)らせん高分子やキラル空間を利用することでプラズモニックナノ結晶をヘリカル集積し、キラルプラズモンによる円偏光二色性増強や円偏光発光を発現させるとともに、選択不斉反応に展開する。(3)ヘテロ界面やバンド位置を緻密に制御したアシンメトリーナノ結晶を合成し、可視・近赤外光誘起電荷分離の高効率・長寿命化を行う。(4)ナノ結晶に対するπ共役分子の空間配置を制御し配位結合で低対称集積することにより、従来にない高効率な指向性エネルギー移動系を構築する。以上の研究を通し、配位アシンメトリー化学ならではの不斉反応場構築や物性発現を行う。
