Title:
ORGANIC COMPOUND, MIXTURE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/152215
Kind Code:
A1
Abstract:
Provided is an organic compound, comprising a structure as represented by chemical formula (1). Also provided is an organic mixture, comprising at least one first compound and at least one second compound, wherein the first compound comprises a structure represented by chemical formula 1, and the second compound is preferably selected from bicarbazole derivatives. The organic compound or mixture can improve the efficiency and service life of a device as a phosphorescent light-emitting host material, and the synthesis process therefor is relatively simple and has a low cost, thus having great application potential and application scope. The organic mixture can balance hole and electron transport rates well, such that the low efficiency roll-off and long service life of an OLED device at a high brightness are achieved. Also provided are a mixture and a composition (a printing ink) comprising the organic mixture, and an organic electronic device, in particular an electroluminescent device.
