Abstract

Hole mobilities in substituted N,N′-bis-(m-tolyl)-N-N′-diphenyl-1,1′-biphenyl-4,4′-diam ine (TPD) derivatives doped in polystyrene (PS), were analyzed by the time-of-flight technique to determine the effect of altering the geometric and electronic structure of TPD. Data were collected as a function of applied field and temperature to yield the energetic and positional disorder parameters defined in the disorder formalism. The impact of the molecular dipole moment on transport properties was also evaluated. The larger molecular dipole moments of the derivatives lead to an increase in the energetic disorder, which contributes to their lower mobilities. However, the dipolar disorder contribution was found to account only partially for the large differences in mobility.
