A benzhydryl radical based on the stability of the organic light-emitting material at room temperature and using the material preparation of the organic electroluminescent device, which belongs to the field of organic light-emitting technology. The present invention in the preparation of the organic light-emitting material, the center of the common characteristic is the carbon free radical, is composed of two C - C covalent bond and a C - N to form a covalent bond. Stability is the light-emitting free radical material in the application of the key nature, connected to the electronic group conducive to stable free radical, in this invention through the nitrogen-containing heterocyclic carbazole, indole, dimethyl acridine and the like in the electronic group to the nitrogen atom is connected directly to the benzyl group, to obtain a stable benzhydryl radical, its stability and PTM, compared with the TTM is greatly improved, and has a room temperature fluorescent. The preparation of the material of the organic electroluminescent device using double thread condition exciton light-emitting, can avoid the traditional organic electroluminescent device in the use of the triplet state exciton, the maximum external quantum efficiency of the device is 0.66%.
