Abstract
An analysis of the existing experimental data on the charge carrier transpo rt in PS and poly(vinyl-carbazole) is performed and the character of tempor al behavior of the effective hole mobility is established fbr the entire ti me range (from the fractions of nanosecond up to tens of seconds) at 300 K. The effective frequency factor is-demonstrated to simply coincide with the frequency of hindered rotation of carbazole groups in paly(vinylcarbazole) . This rotation is established to be the only channel for the modulation of electron hopping by the molecular motions in the polymers under discussion .
