Abstract
An organic monomolecular white light material, a manufacturing method for the same, and an OLED element are provided. The organic monomolecular white light material has a room temperature phosphorescence emission property in a solid state, and can trap triplet exciton to achieve high efficient luminescence. Also, that has a higher thermal decomposition temperature and glass transition temperature, and the synthetic method and purification process thereof are simple. It has the advantages of mild reaction condition and high yield, and the thermal properties, luminescent properties, white-light color purity, etc of a final product can be adjusted by connecting to different aromatic fused ring or aromatic heterocyclic ring groups. In the OLED element, the organic monomolecular white light material is used as an emitting layer, and the emitting layer has a high luminous intensity and a good stability, thus the luminous efficiency and working life of the OLED element achieve practical requirements.
