Platinum(II) Complexes of Nonsymmetrical NCN-Coordinating Ligands: Unimolecular and Excimeric Luminescence Properties and Comparison with Symmetrical Analogues.

ABSTRACT: A series of seven new platinum(II) complexes PtLⁿCl have been prepared, where Lⁿ is an NCN-coordinating ligand comprising a benzene ring 1,3-disubstituted with two different azaheterocycles. In PtL^1-5Cl, one heterocycle is a simple pyridine ring, while the other is an isoquinoline, a quinoline, a pyrimidine (L¹, L², L³), or a p-CF₃- or p-OMe-substituted pyridine (L⁴ and L⁵). PtL⁶Cl incorporates both a p-CF₃ and a p-OMe-substituted pyridine. The synthesis of the requisite proligands HLⁿ is achieved using Pd-catalyzed cross-coupling methodology. The molecular structures of six of the Pt(II) complexes have b
