简化蓝色热激活延迟荧光(TADF)二极管时,电荷通量平衡和界面优化是两个核心问题,这反映了对载流子传输材料(CTM)的更严格的要求,这是电荷传输和淬灭抑制之间矛盾的体现。对分子间相互作用的要求相反。在此,以苯基苯并咪唑(PBI)为核心,被两个二苯基氧化膦(DPPO)取代,形成了六种双包封的电荷-激子分离(CES)型电子传输材料(ETM),其总名称为xy PBIDPO。通过调节DPPO基团的取代位置,将其共振和空间效应两个功能进行了整合和优化,以增强带电部分的封装,而无需降低电活性。结果,在xy PBIDPO中,mm PBIDPO凭借其两倍的台面取代结构和大致对称的构型成功实现了良好的电性能和界面相互作用抑制之间的平衡,从而实现了2.8 eV的良好电子亲和力,高电子迁移率。 10 –6 cm 2 V –1 s –1的水平和有效的PBI核心封装。因此,mm PBIDPO被用来极大简化蓝色TAD
