Title:
NITROGEN-CONTAINING COMPOUND, ORGANIC ELECTROLUMINESCENCE DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/135182
Kind Code:
A1
Abstract:
The present application belongs to the technical field of organic materials, and provided therein is a nitrogen-containing compound, comprising at least three directly or indirectly linked fused ring systems. A first fused ring system is a fluorenyl group spiro-linked by adamantane, and adamantyl can greatly increase the electron cloud density of a conjugated structure of the first fused ring system by means of a hyperconjugation effect, which can increase hole mobility. The three fused ring systems enable the nitrogen-containing compound of the present application to have a high first triplet energy level so that the nitrogen-containing compound of the present application is suitable as the main body material of an organic light-emitting layer in an organic electroluminescence device. Further provided in the present application are an organic electroluminescent device comprising the described nitrogen-containing compound and an electronic apparatus, and the described nitrogen-containing compound can improve the performance of the organic electroluminescent device.
