Abstract： |
The invention relates to a tetraphenylmethane derivative, the structure formulation is R1-R4 hydrogen atom, 1-30 carbon atom number alkyl and vinyl, 6-50 carbon atom number substituted or unsubstituted aryl, associated aryl, condensed-nuclei aryl, 4-50 carbon atom number substituted or unsubstituted heterocyclic radical aryl with N, benzo heterocyclic radical aryl, 1-50 carbon atom number alkyl, vinyl, aryl or group which comprises heterocyclic radical aryl, wherein n1-n4 is 1-3 integer. The invention can be used for the luminescent layer of the organic electroluminescent device as the main body material of the triplet state luminescent dye, which is provided with high energy and high stability, can stop the energy reverse delivery process between the dye molecule and the main body material molecule, improves the lightness and efficient of the organic electroluminescent device, and improves the life of the organic electroluminescent device. |
