摘 要: 合成两种二苯基磷酰基修饰的噁唑类化合物——2-[5-(二苯基磷酰基)吡啶-2-基]-4,5-二-(4-甲苯基)噁唑(OPO1)和4,5-双[4-(二苯基磷酰基)苯基]-2-(吡啶-2-基)噁唑(OPO2)。经过测试表征,研究其热力学、光物理和电化学性质,同时经过密度泛函理论计算,结果与实验相符。这两种化合物具有很好的热稳定性和极高的玻璃化转变温度,以OPO1为电子传输材料制备的器件效率也十分稳定,没有明显的效率滚降。研究首次以2-吡啶噁唑为母核应用于电子传输材料中,并用二苯基磷酰基修饰,取得了一定的效果。

Abstract: Two diphenylphosphoryl substituted oxazoles, namely 2-[5-(diphenylphosphoryl)pyridin-2-yl]- 4,5-dip-tolyloxazole (OPO1) and 4,5-bis[4-(diphenylphosphoryl)phenyl]-2-(pyridin-2-yl)oxazole (OPO2) were synthesized and developed as electron transport materials. The thermodynamics, photo physical and electrochemical characteristics of the compounds were investigated systematically, which match well with the density functional theory (DFT) calculations. These two compounds have good thermal stability and very high glass transition temperature, the devices without obvious roll-off were stable by using OPO1 as electronic transport materials. For the first time, 2-pyridoxazole is used as nuclear structure in the electron transport material. By modifyed with diphenylphosphoryl, the compounds exhibit good thermal stability.
