C^N*N cyclometalated platinum(II)L complexes with functionalized acetylide ligands were prepared (L = phenyl, pyrenyl or naphthalimide acetylides). The absorption of the pyrene and naphthalimide derived Pt(II) complexes in the visible region of the spectr

A series of tridentate cyclometalated platinum(II) complexes (C ∧*)PtL (L = Cl or acetylide) featuring a fused five-six-membered metallacycle were synthesized. The structure of the complexes was confirmed by X-ray crystallography. In contrast to the C ∧N∧N platinum complexes with a fused five-five-membered metallacycle, the platinum coordination in C ∧N*N complexes is much closer to a square planar geometry. The photophysical properties of the complexes were studied. The geometrical change from C∧N∧N to C ∧N*N led to a substantial improvement in phosphorescence efficiency of the complexes with an acetylide ligand in solution at room temperature. For example, the quantum yield of (C∧N *N)PtCCPh was measured to be 56%, demonstrating a big jump from 4% reported for (C∧N∧N)PtCCPh.
