Tuning side chain and main chain order in a prototypical donor-acceptor copolymer

Marcel Schubert, Johannes Frisch, Sybille Allard, Eduard Preis, Ullrich Scherf, Norbert Koch, Dieter Neher

The recent development of donor–acceptor copolymers has led to an enormous improvement in the performance of organic solar cells and organic field-effect transistors. Here we describe the synthesis, detailed characterisation, and application of a series of structurally modified copolymers to investigate fundamental structure–property relationships in this class of conjugated polymers. The interplay between chemical structure and optoelectronic properties is investigated. These are further correlated to the charge transport and solar cell performance, which allows us to link their chemical structure to the observed physical properties.
