The invention belongs to the technical field of organic optoelectronic materials, and in particular relates to an organic optoelectronic material and its preparation method and application. The organic optoelectronic material has a molecular structure conforming to the formula (1): Wherein, R 1 and R 2 are C 6-18 aromatic heterocyclic groups or contain at least one C 6-18 aromatic heterocyclic groups in O, S, N, R 3 is isopropyl or tert-butyl, The product of the present invention adopts thiophene and furan as a matrix with a phosphine-oxygen bond as a bridge, and has good molecular stability. The photoelectric material with polarity transmission ability balances the transmission of holes and electrons in the light-emitting layer and improves the luminous efficiency. The spatial structure is a twisted non-planar structure, which can effectively avoid the close accumulation of molecules and has good thermal stability. The prepared OLED device, It has the effect characteristics of high brightness, high efficiency and low voltage. |
