Claim Text:
1. A regioregular donor-acceptor copolymer comprising a regioregular conjugated main chain section, said regioregular conjugated main chain section having a repeat unit that comprises a pyridine of the structure wherein: wherein each Ar is independently a substituted or non-substituted aromatic functional group, or each Ar is independently nothing and the valence of its respective thiophene ring is completed with hydrogen, each R is independently hydrogen or a substituted or non-substituted alkyl, aryl or alkoxy chain; X is C, Si, Ge, N or P; and the charge carrier mobility of the regioregular donor-acceptor copolymer is greater than the charge carrier mobility of a regiorandom donor-acceptor copolymer of similar composition.
