Title:
ORGANIC LIGHT-EMITTING COMPOUND, PREPARATION METHOD, AND ORGANIC LIGHT-EMITTING DEVICE CONTAINING COMPOUND
Document Type and Number:
WIPO Patent Application WO/2020/073480
Kind Code:
A1
Abstract:
The present application relates to the technical field of organic light-emitting materials, and relates in particular to an organic light-emitting compound, a preparation method therefor, and an organic light-emitting device containing the compound. Provided by the present application is an organic light-emitting compound: an acridine functional group having high electron hole transport efficiency is combined with a triarylamine having excellent hole transport performance to form a class of compounds having high thermal stability and excellent light emission efficiency; the introduction of different substituents may change electronic transition such that the light emission peak position thereof may be adjusted; a red light device manufactured by using the material of the present application may meet the needs of industrial production. The preparation method for an organic light-emitting compound provided by the present application has a simple preparation method and is suitable for industrial production; in addition, a compound having better performance may be prepared by means of adjusting the ratio of the amounts of the reactants as well as reaction time and temperature. The organic light-emitting device provided by the present application has excellent light-emitting efficiency, brightness, resolution, and a long service life.
