Disclosed herein are several organic compounds having electron-transporting and/or hole-blocking performance and their preparation method and use and the OLEDs comprising the organic compound. The organic compounds exhibit high ionization potential (IP), electron affinity (Ea), glass transition temperature (Tg) and high electron mobility, and are a kind of good electron-transporting material with good hole-blocking ability. The devices comprising these compounds as one of the emitting layer, electron-transporting layer (ETL) and hole-blocking layer (HBL) show improved efficiency and better color purity.
本文披露了几种具有电子传输和/或阻挡空穴性能的有机化合物,以及它们的制备方法和用途,以及包含该有机化合物的OLED。这些有机化合物具有高电离势(IP)、电子亲和力(Ea)、玻璃化转变温度(Tg)和高电子迁移率,并且是一种具有良好阻挡空穴能力的良好电子传输材料。包含这些化合物作为发射层、电子传输层(ETL)和阻挡空穴层(HBL)之一的器件显示出提高的效率和更好的色纯度。
