Abstract
4-(2,2-Diphenylethenyl)-N,N-bis [(4-methyl) phenyl]aniline was synthesized from bromodiphenylmethane and 4-(N,N-bis-4-methylphenyl) aminobenzaldehyde via Wittig-Horner reaction.The relationship between the 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 was conducted under the above conditions and an average yield of 96.79% was obtained.The compound was characterized by means of1HNMR,13CNMR,FTIR 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,with V 0=550 V,V R=10 V,R d=10 V/s,E1/2=0.6 lux·s.
