Abstract

Hole mobilities have been measured in N,N'-bis(2,2- diphenylvinyl)-N,N'-diphenylbenzidine (ENA) doped into a series of different polymers. At room temperature, the mobilities vary by over four orders of magnitude. The results are described within the framework of a formalism based on disorder. The formalism is based on the assumption that charge transport occurs by hopping through a manifold of localized states that are distributed in energy. The key parameter of the formalism is the energy width of the hopping site manifold or DOS (density-of-states). For ENA doped polymers, the widths are between 0.084 and 0.118 eV. The width is described by an argument based on dipolar disorder. The argument is based on the assumption that the width is comprised of a dipolar component and a van der Waals component. The dipolar component is comprised of a dopant contribution due to the ENA and a polymer contribution. The differences in mobilities of these materials are attributed to differences in the polymer dipolar components.
