Paper Abstract

Thin film morphological studies using a number of techniques including AFM and XRD have revealed some interesting molecular self-assembled pattern in the synthesized −DBAB− block copolymer, and this is very different from the corresponding simple D/A blend. It was also observed that the thin film processing conditions affect the morphologies dramatically. The earlier observed much better photovoltaic properties of a −donor-bridge-acceptor-bridge type block copolymer versus the corresponding donor/acceptor blend has been attributed to morphological improvements in spatial domain.
