A ruthenium(II) tris(2,2′-bipyridine) derivative possessing a triplet lifetime of 42 μs

Abstract

Grafting an ethynylated-pyrene moiety to a Ru(II) or Os(II) polypyridine complex perturbs the photophysical properties of the metal fragment and, when the relevant energy levels are properly balanced, provides a 115-fold prolongation of the triplet lifetime.
