This Letter reports the synthesis and optical properties of polythiophenes prepared in cholesteric liquid crystal (CLC) medium. The polythiophenes prepared from achiral monomers in the CLC display consistent optical activity. In the first step of this research, we prepared CLCs for a reaction solvent. Next, Stille-type polycondensation reaction in the CLC was carried out. The resultant polymers show intense circular dichroism (CD). The CD results suggest that the polymers form a chiral structure.
