The steady-state and transient photoexcitation dynamics...

(charged and neutral) of thin films of poly-(3-alkyl thiophenes) with a regioregular or a regiorandom structure forming lamellae or simply polymeric chains have been investigated in detail by Vardeny and coworkers. While in regiorandom films intrachain photoexcitations dominate, the primary excitons in the regioregular films have large interchain components. (Z. V. Vardeny et al., September 16, Adv. Funct. Mater. 2002, 12, 587-597)
