The extent of photoinduced energy-transfer between [Ru(bipy)3]2+ and [Os(bipy)3]2+ units attached to either end of a deca(oxoethylene) 33-atom chain can be used to show how the distribution of end-to-end distances in the ensemble of conformations changes in different solvents.
在不同溶剂中,[Ru(bipy)3]2+ 和 [Os(bipy)3]2+ 单元附着在一个 33 个原子的十(氧乙烯)链的两端之间的光诱导能量转移程度可以用来展示构象集中的端对端距离分布是如何变化的。
