以杯[4]芳烃为母体的新型电子传输材料及其OPC的特性(英文)

A Novel Electron Transport Material Based on Calix[4]arene and Its Properties as OPC

设计并合成制备了一系列环化结构的新型电子传输材料:杯[4]芳烃类环化联苯醌化合物(环化结构 ETM),并通过CTL、IR、核磁、质谱等手段确认了分子结构。用环化结构ETM与空穴传输材料和电荷产生材料配合,制作了多组分单层结构有机光导体,并对其静电照相性能进行了全面考察。实验结果表明,分子结构中带有两个联苯醌单元、取代基为异丙基以及环对位丙醚化的环化结构ETM在常规有机溶剂中具有良好的溶解度,与树脂PC和Vylon200(一种聚酯)的相容性良好,均可以实现40wt%及以上的高浓度掺杂。并且,这种新型的环化结构 ETM的整体性能优于 TNF,而且可以在较低掺杂浓度下,实现良好的静电照相性能。

It designed and prepared a series of new electron transport molecules, i.e., a ring-structured diphenoquione based on calix[4]arene(termed as, hereinafter, ring-structured ETM). And, molecular structure was confirmed by using CTL, IR, NMR, MS and so on. Single-layered multi-component OPC devices were made by incorporating the ring-structured ETM with properly chosen HTM and CGM, and their xerographic performances were systematically investigated. Experimental results indicated that molecules with two diphenoquione units, isopropyl group and p-propyl ether group were of good solubility in common organic solvents, excellent compatibility with polymers, such as PC and Vylon200(a polyester) and enabled doping at high concentrations, say, over 40wt%. In addition, the new ring-structured ETM showed improved performances over TNF and was characterized of better xerographic properties at relatively low concentrations.
