The electric field dependence of drift mobility was obtained by Time Of Flight (TOF) technique on several hole transport molecules in polymer binder. The electronic properties of carrier transport molecules obtained from experiment and molecular orbital calculation were compared to the electric field dependence of drift mobility. The slope of drift mobility clearly showed the linear dependence on dipole moment of CTM.
