摘要

We report new divalent osmium complexes that feature strong red metal-to-ligand-charge- transfer (MLCT) phosphorescence and electrophosphorescence. The general formula of the complexes is Os (II)(NN) 2L-L, where NN is either a bipyridine or a phenanthroline and LL is either a phosphine or an arsine. New polypyridyl ligands synthesized are 4, 4'-di (biphenyl)- 2, 2'-bipyridine (15) and 4, 4'-di (diphenyl ether)-2, 2'-bipyridine (16), and the 1, 10- ...
