Abstract

Atropisomeric scaffolds offer the possibility to predictably position donor and acceptor groups in specific spatial relationships. Herein, a configurationally stable 1,2’-binaphthyl linkage was employed to place a ruthenium(II) tris-(2,2’-bipyridine) complex in proximity to an anthracene moiety to explore how photoinduced triplet-triplet energy transfer can proceed across this type of molecular bridge. An efficient synthesis provided the ruthenium(II)-anthracene dyad with high yields, which allowed to determine characteristic features for the intramolecular energy transfer.

通过atrosomomer分子桥的光诱导能量转移

收缩异构体支架提供了在特定空间关系中可预测供体和受体基团位置的可能性。本文采用结构稳定的1,2 ' -联萘键将钌（II）三-（2,2 ' -联吡啶）配合物放置在蒽基团附近，以探索光诱导的三重态-三重态能量转移如何通过这种类型的分子桥进行。高效的合成为钌(II)-蒽二偶体提供了高收率，从而可以确定分子内能量转移的特征。
