A chiral indolocarbazole light-emitting material, an organic electroluminescent device and application

Abstract

The application belongs to the technical field of organic electroluminescence, and particularly relates to a chiral indolocarbazole light-emitting material, an organic electroluminescent device and application. The chiral indolocarbazole light-emitting material introduces [2.2] paracyclophane into a traditional indolocarbazole skeleton in a central fused conjugated form, and the spatial conjugation effect of the molecular center can effectively adjust the indolocarbazole molecular energy level and the excited state, so that the electron delocalization can be realized without increasing the traditional planar conjugated length, the emission spectrum is red-shifted, and the chiral indolocarbazole light-emitting material can be used as a light-emitting layer in a circularly polarized organic light-emitting diode.
