专利号:WO-2025097667-A1 优先权日:2023-11-08 标题:Mixture, composition, and use thereof in electronic device 发明人:PAN JUNYOU; ZHANG HAO 权利人:ZHEJIANG BRILLIANT OPTOELECTRONIC TECH CO LTD 摘要:Disclosed is a mixture, comprising: at least one first compound H1 represented by formula (I) and at least one second compound H2, the second compound H2 being preferentially selected from bicarbazole derivatives. An organic compound or mixture of the present invention, when used as a phosphorescent light-emitting host material, can improve the efficiency of devices and the service life of devices. In particular, an organic mixture can strike a good balance between electron holes and electron transport speed, and achieve low efficiency roll-off and a long service life of OLED devices at high brightness. Moreover, the material provided by the invention has a relatively simple synthesis process and is low cost, so that the material has huge application potential and application range. The invention further relates to a composition and an organic electronic device, and in particular relates to an organic electroluminescent device.
