新型联苯醌衍生物静电照相性能的研究

Study on Xerographic Performances of Diphenoquinone Derivatives

本研究合成了一系列联苯醌衍生物并对其结构进行确认,同时以合成的联苯醌衍生物作为电子传输材料(ETM)与空穴传输材料(HTM)、电荷产生材料(CGM)和成膜树脂进行匹配,制备了多组分掺杂的单层结构有机光导体.研究结果表明,光导体的感光度强烈地依赖于ETM的掺杂浓度,半衰曝光量首先随ETM浓度的增大而减小,在掺杂浓度为10%时降到最小,并趋于稳定.2,5,5′-三叔丁基联苯醌在所研究的联苯醌衍生物中性能最为优秀,在780 nm处半衰曝光量为2.2μJ/cm2.

A series of diphenoquinone derivatives were synthesized and their molecular structures were confirmed by using CLT, IR, NMR and MS. The diphenoquinone derivative used as ETM was doped along with other components, e.g., HTM and CGM, into a polymer matrix, to form a single-layered organic photoreceptor. It was found that photosensitivity was strongly dependent on ETM concentration. The half decay exposure firstly decreased with ETM＇ s concentration and then increased at higher ETM concentrations after having reached a minimum at 10%, and finally a plateau was reached after that. 2,5,5＇-tritert-butyl diphenoquione was found the best among other investigated diphenoquinone derivatives and the half decay exposure was 2.2 μJ/cm^2 at 780 nm wavelength.
