Synthesis and hole transport property of a novel triphenylamine substituted stilbene derivative

A novel hole transport material (HTM) of triphenylamine substituted stilbene derivative of 4,4'-bis-[2-[4-[N-(phenyl-4-methoxyphenyl)-amino]-phenyl-1-yl]-vinyl-1-yl] -1,1'-biphenyl (DSPAVBi) was synthesized. The chemical structure was characterized by IR spectrum, 1H NMR spectroscopy and elemental analysis. The electronic structure was studied by UV-vis absorption and cyclic voltammetry methods. The photosensitivity of the dual-layer photoreceptor containing oxotitanium phthalocyanine (TiOPC) as the charge generation material (CGM) and DSPAVBi as the charge transportation material (CTM) was higher than that containing its parent compound 4,4'-bis-[2-[4-(N,N-diphenylamino)-phenyl-1-yl]-vinyl-1-yl]-1,1'-biphenyl (DPAVBi) as CTM, in agreement with the results calculated with semi-empirical PM3 method
