Summary: | A novel series of cyclometalated platinum(
ii
) complexes bearing acyclic diaminocarbene (ADC) ancillary ligands were designed and prepared. Their photophysical properties were systematically studied through experimental and theoretical investigations. All complexes exhibit green phosphorescence with a quantum efficiency of up to 45% in 2 wt% doped PMMA film at room temperature. The complexes are used as light-emitting dopants for organic light-emitting diode (OLED) fabrication. The devices displayed a green emission with a maximum current efficiency of 2.9 cd A
−1
and a luminance of 2700 cd m
−2
. These results show that these cyclometalated platinum(
ii
) complexes can be used as efficient green emitting components of OLED devices.
