A polymer compound comprising a structural unit represented by the formula (1):n n[wherein nR 1 , R 2 , R 3 and R 4 each independently represent an alkyl group, an aryl group or a monovalent heterocyclic group, and these groups optionally have a substituent. nTwo rings A may be the same or different, and represent a thiophene ring, a benzothiophene ring or a thienothiophene ring. n represents 1 or 2, and X represents a halogen atom, an alkyl group, an alkoxy group, an alkylthio group, an amino group, an aryl group, a monovalent heterocyclic group, an alkenyl group or an alkynyl group, and these groups optionally have a substituent. When n is 2, two groups X may be the same or different.]. |
