Synthesis and Luminescence Properties of Ru2/Cu, Ru2/Ni, and Ru2/Os Mixed Metal Polypyridine Complexes Bound by 1,3,5-Triethynylenebenzene

Abstract

Abstract Novel polypyridine metal complexes have been prepared, wherein two (terpy)2Ru units and one (bipy)3M (M = Cu, Os) or (bipy)Ni(H2O)4 unit (terpy = 2,2′:6,6′-terpyridine, bipy = 2,2′-bipyridine) are bonded to 1,3,5-positions of a benzene ring via ethynylene bridges. Photophysical study of these hetero trinuclear complexes has indicated effective electronic energy transfer between the metal components can take place.
