Abstract

The invention provides a platinum complex, application thereof and an organic photoelectric device comprising the platinum complex. The platinum complex comprises a structural fragment as shown in a formula A. Divalent platinum is introduced into methylpyridino imidazole carbene so that the obtained complex has relatively high stability and luminous efficiency, is narrow in luminous interval and can be used as a blue phosphorescence luminescent material to be applied to an organic photoelectric device in a long-wavelength blue light interval. The platinum complex has the advantages of high efficiency, low energy, good chromaticity and the like when being used as a blue phosphorescence luminescent material, and can achieve the types of emitting blue light and improving the efficiency of devices.
