Optically active polythiophene with a high stere regularity was synthesized for the first time by using a Rieke zerovalent zinc catalyst. An optically active polymer having more than 93 of Head-Tail linkages was obtained from 32S-2-methylbutoxyethylthiophene. Electrical and optical properties of the Head-to-Tail polymer were much superior to those of random-type polymer derived from the same--monomer and the third order non-linearity k3 reached a high value of 10exp -7 esu.
