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。
A series of novel electron-transporting materials with cyclized structure were designed and synthesized: calix [4] arene-based cyclized diphenoquinone compounds (cyclic structure ETM), and their molecular structures were confirmed by CTL, IR, NMR and MS . The cyclic structure ETM was used in combination with the hole transporting material and the charge generating material to fabricate a multi-component monolayer organic photoconductor. The electrophotographic properties of the organic photoconductor were investigated comprehensively. The experimental results show that the cyclodehydrated ETM with two diphenoquinone units in the molecular structure and the isopropyl group and the cyclopropane etherification ring has good solubility in the conventional organic solvents. Compared with the resin PC and Vylon200 ( A polyester) good compatibility, can achieve 40wt% and above the high concentration of doping. Moreover, the new cyclic structure ETM is superior to TNF in overall performance and achieves good electrophotographic performance at lower doping concentrations.
