A Novel Electron Transport Material Based on Calix4arene and Its Properties as OPC

摘要

It designed and prepared a series of new electron transport molecules, i.e., a ring-structured diphe-noquione 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.
