Document Type and Number:
WIPO Patent Application WO/2021/135183
Kind Code:
A1
Abstract:
The present application relates to the technical field of organic materials, and provides an organic compound. A novel compound for an organic electroluminescent device is obtained by bonding and combining an adamantane spiro fluorenyl group and an anthryl group. In the compound, the density of electron cloud on fluorenyl is greatly increased by adamantane in the adamantane spiro fluorenyl group by means of hyperconjugation, so that the HOMO energy level of the compound gets shallow, the hole mobility is enhanced, the adamantane spiro fluorenyl group and the anthryl group both have high hole mobilities, and when the adamantane spiro fluorenyl group and the anthryl group are bonded, the hole mobility of molecules, taken as a whole, is further improved so that the working voltage of the device is reduced and the light emitting efficiency is improved. The present application also provides an electronic element and an electronic apparatus comprising the compound. The organic compound can improve the performance of the electronic element.
