Transport Studies of Conjugated Star Polymers
Abstract
Higher dimensionality "star" polymers provide new properties beyond those found in their linear analogs. We report on transport properties of star polymers with a conjugated hyperbranched triphenylamine core and either polyhexylthiophene arms (SPT) or polyethylenedioxythiophene-didodecyloxybenzene arms (SPEB). Photophysical studies indicate the quantum states for core and arms do not delocalize sufficiently to form a single supramolecular state but rather the core and arms have separate states. The charge carriers remain localized due to a combination of disorder induced localization and low transport dimensionality. Temperature dependent conductivity reveals a common electronic transport dimensionality for films cast from solution doped polymer.
