• Reactive functional group
• Hole drift mobility
• Ionization potential

Derivatives of N,N'-bis(2.2-diphenylvinyl)-N,N'-diphenylbenzidine containing reactive functional groups were synthesized by the multi-step synthetic rout. The materials were examined by various techniques including differential scanning calorimetry, UV and fluorescence spectrometry, electron photoemission and time of flight techniques. The electron photoemission spectra of layers of the amorphous materials showed the ionization potentials of 5.35 eV. Hole drift mobilities in the layers of bisphenol Z pol carbonate containing 33-50% of the derivatives of N,N'-bis(2,2-diphenylvinyl N,N'-diphenylbenzidine range from 1.6x10(-5) to 1.3x10(-4) cm(2)/Vs at high electric fields.
