successfully assembled by embedding coordination sites in the ligand backbone. The angle between the two arms at position 4 of the central terpyridine (tpy) units increased after complexation with metal ions, leading to precise control over the topology.
通过在
配体主链中嵌入配位位点,成功组装了两个具有双层和三层同心七边形结构(分别为
DA和TA )的巨型
金属大环。与
金属离子络合后,中心三联
吡啶(tpy)单元4号位的两个臂之间的角度增加,从而实现对拓扑结构的精确控制。
