text] A new copper-complexed rotaxane is described. It consists of a two-coordination site ring threaded by a sterically non-hindering 2,2'-bipyridine derivative. An electrochemical signal (oxidation or reduction of the copper center, Cu(I) or Cu(II)) induces rearrangement of the system. By using long and flexible linkers between the stoppers and the central complex, ligand exchange is fast, which leads
[反应:见正文]描述了一种新型的铜络合物轮烷。它由两个配位位点环组成,这些位点环上有空间无阻碍的2,2'-联吡啶衍生物。电化学信号(铜中心,Cu(I)或Cu(II)的氧化或还原)引起系统重排。通过在塞子和中央复合物之间使用长且灵活的连接子,配体交换很快,从而导致响应时间短(在毫秒级甚至更低)。
