Thiophene derivative, method for producing same, and polymer of thiophene derivative

Abstract

A novel polymer which has high solubility and good processability and is suitable as an electrically conductive material, and a novel compound which is a starting material of the polymer. The novel compound to be used as a starting material is a thiophene derivative represented by formula (I) shown below, In the formula (I), A is S; and B is R2 (R2 is an alkylene group having a carbon number of 2 to 3 and optionally having a substituent), provided that A and B are intramolecularly cyclized to form, together with the thiophene group, a bicyclic heterocyclic structure. The novel polymer that is produced by polymerizing the thiophene derivative is suitable as an electrically conductive material.
