utilized as efficient hole‐blocking materials for phosphorescent organic light emitting diodes (OLEDs). Some of these compounds showed a performance surpassing that of the current standard, bathocuproine. The new compounds were easily synthesized in a modular fashion from a previously reported 3‐stannyl benzosilole building unit. Studies on the properties of these compounds in solution and in the solid state
面向多样性的合成策略使我们能够设计一系列包含多个苯并甲硅烷基单元的共轭分子,这些共轭分子可用作磷光有机发光二极管(OLED)的有效空穴阻挡材料。这些化合物中的一些表现出超过当前标准浴铜嘌呤的性能。新化合物很容易以模块化方式由先前报道的3-锡烷基苯并甲硅烷基建筑单元合成。对这些化合物在溶液和固态下的性质的研究表明,它们具有高电子亲和力,高电离势能,并形成显示出高电子漂移迁移率的稳定非晶膜。还研究了它们的分子性质与OLED器件性能效率之间的相关性。
