Abstract
Polaron dynamics in a system of highly ordered conjugated polymer chains is investigated based on the tight binding model. With the interchain coupling enhancing, it takes longer time for the electron added to the system to induce a localized polaron state. Beyond a certain strength of the interchain coupling, the electron evolves into a two-dimensional delocalized polaron state. Dynamical simulations suggest that the well-ordered organic molecule systems with two-dimensional polarons exhibit higher mobilities than the systems with intrachain localized polarons, as also suggested by earlier experiments.
