摘要：
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.
