<p>A novel polythiophene in which the backbone shows intensive absorption in the ultraviolet to visible regions and the polymer chain by itself has optical activity, characterized by comprising, as repeating units, thiophene rings which have a chiral substituent and are represented by general formula (I) (wherein R1 and R2 are the same or different and each represents hydrogen or an organic group, provided that at least one thereof represents enantiopure alkyl having a branch in the β-position; and n, indicating the number of repeating units, is 10 to 100,000).</p> |
