Abstract
The present invention relates to light-emitting materials for light-emitting diodes. The structure for the light-emitting materials is shown in Formula I. The platinum (II) complexes of the present invention show high emission quantum efficiency, good thermal stability and low quenching constant, thus can be used for producing red light OLED with high efficiency and low efficiency attenuation.
