Abstract :
We Have studied acceptor substituted poly(3-butyl)thiophene (PBT) in order to examine the usefulness of the acceptor as an intrinsic charge trap under laser excitations. We have found considerable enhancement of the slow decay component of the transient photoconductivity upon acceptor substitution, which is attributed to charge trapping.
