Platinum(II) and copper(I) 1-(2-diphenylphosphino-1-naphthyl) isoquinoline complexes: Synthesis and phosphorescence at ambient conditions

Abstract

The compounds Pt(quinap)(CN)(2), Cu(quinap)(2)(+) and [Cu(quinap)I](2) with quinap = 1-(2-diphenylphosphino-1- naphthyl) isoquinoline were synthesized. Quinap is a bidentate ligand which contains a isoquinoline and an arylphosphine group with CT acceptor properties. Accordingly, the Pt(II) and Cu(I) quinap complexes are characterized by a phosphorescence originating from the lowest-energy MLCT triplets with some IL admixture. (c) 2008 Elsevier B.V.
