4-(2,2-diphenylethenyl)-N,N-bis[(4-methyl)phenyl] aniline was synthesized with bromodiphenylmethane and 4-(N,N-bis-4-methylphenyl) aminobenzaldehyde via Wittig-Horner reaction. The relationship between yield and reaction conditions, such as reaction time, temperature and the molar ratios of raw material was investigated and the yield could reach 97.94%. The 10 times amplification synthesis were conducted under the above conditions and got the average yield of 96.79%. The compound was characterized by 1H NMR, 13C NMR, FT-IR and MS. The highest occupied molecular orbital (HOMO) level and the lowest unoccupied molecular orbital (LUMO) of the compound were investigated by the cyclic voltammetry experiment, respectively. The organic photoconductive devices based on the titled compound as hole-transporting materials showed excellent xerographic performance, V0 = 550V，VR = 10 V，Rd = 10 V/s, E1/2 = 0.6 lux?s.
