Fast and simple synthesis of hole transporting materials inspired by “click-chemistry” was performed. By employing hydrazone chromophores, high hole drift mobility (up to 0.0013 cm2 V−1 s−1) and controllable morphology was achieved.
在“点击化学”的启发下,对空穴传输材料进行了快速,简单的合成。通过使用发色团,实现了高空穴漂移迁移率(高达0.0013 cm 2 V -1 s -1)和可控的形态。
Methyl substituent effects on the HOMO and LUMO energy levels, and the ability to transport charge and form stable molecular glasses of 4-(diphenylamino) benzaldehyde phenylhydrazones were investigated. Thermal properties, HOMO and LUMO energy levels, and hole mobility values are dependent on the number of methyl substituents and their position in the investigated transporting materials. Surprisingly, however, the presence of methyl groups at any position negatively affects the hole drift mobility of the molecularly doped polymers containing those hydrazones.
