Synthesis and Photoconductive Properties of N,N-Bis(4-methylphenyl)-4-[2-(4-methylphenyl)ethenyl] benzenamine

The compound N,N-bis(4-methylphenyl)-4-benzenamine(Ⅲ)was synthesized from benzenamine and 4-met hylbenzyl bromide via three steps,namely Ullmann reaction,Vilsmeier reaction and Wittig reaction.The structure of the target compound was identified by IR,1HN MR and MS.Using Ⅲ as charge transfer material and titanium oxide phthalocyanine as charge generation material,a double-layered photoreceptor cell was fabricat ed and some parameters were obtained.Under the charge voltage of 1000 V,charge a cceptance of the cell reaches 935 V,residual potential is 60 V and its photosens itivity is 10 (lx·s)-1 with dark decay of 111 V/s.All the parameters show that the synthesized substance is an excellent charge transfer material.
