摘要：
The photoluminescent properties of mono- and polynuclear cyclometalated platinum(II) complexes are discussed. Spectroscopic studies have revealed weak intra- or intermolecular metal-metal and ligand-ligand interactions that are affected by the molecular structure and microenvironment. The structure-emission relationships observed in these platinum(II) complexes are described and comparisons with palladium(II) analogues regarding the structural and photoluminescent properties are highlighted. With judicious modification of cyclometalated and/or ancillary ligands, robust platinum luminophores with tunable emission energies and lifetimes have been synthesized. These complexes can be employed as luminescent sensors and electrophosphorescent materials in organic light-emitting devices (OLED).
