Abstract

Provided are an organic compound, an electroluminescent material and use thereof. The organic compound has a structure as shown in Formula I. Through the molecular structure design, the organic compound has a deep LUMO energy level, which can reduce electron injection potential barrier and improve electron injection ability; it has a deep HOMO, which can effectively block holes and make more electron-holes recombine in the light-emitting layer; it has a high triplet energy level E, which can effectively block light-emitting layer excitons. The molecule has a twisted spiro structure, which can reduce molecules stacking, avoid crystallization, show excellent thermal stability and film stability, and help improve luminous efficiency and lifetime. As electroluminescent materials, the organic compound is suitable for an electron transport layer and/or a hole blocking layer of OLED devices and can reduce voltage and power consumption, improve luminous efficiency and working lifetime to have better comprehensive performance.
