Chiral alkyl polythiophenes

Polythiophenes with substituents other than alkyl groups at the 3 position have been prepared by the polymerization of substituted monomers. Many of these polymers have been substituted alkylthiophenes (8) where example side chains are (R =) —C6H5 (86—89), —OCH3 (68), —NHC(0) (CFF)10CFF (68), and —0S02(CH2)3CH3 (90). Chiral side chains have also been employed (91,92). Poly(3-alkoxythiophenes) (9) (93—95) and poly(3-alkylthiothiophenes) (10) (95—98) have been prepared by both chemical and electrochemical methods.
