Seven platinum(Ⅱ) complexes containing 2-phenylisoquinoline or its derivatives were prepared and the structures and properties of complexes were characterized by 1H/¹³C NMR,TGA,X-ray single crystal diffraction,CV,UV-Vis and PL etc.The results show that these platinum(Ⅱ) complexes keep planar coordination geometry around Pt atom,and exhibit red phosphorescence from the metal-to-ligand charge-transfer(MLCT)(407,444,463 nm) and ligand center(LC)(353,363,376 nm) of mixed-state with quantum efficiency of 0.02~0.06 and lifetimes of 1.78~3.33 μs at room temperature in the DCM solution.Steric hindrance of the peripheral substituent effectively inhibits the intermolecular interaction.
- Pt(Ⅱ) complex,
- phenylisoquinoline,
- red emitting,
- square-planar configuration,
- intermolecular interaction
