THIENOPYRAZINE DERIVATIVE HAVING p-SULFANYL-SUBSTITUTED PHENYL GROUPS AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a novel thienopyrazine derivative useful as a monomer which serves as a raw material of a low-bandgap (Eg<1.5 eV) conjugated polymer, and a method for producing the same.SOLUTION: Provided are a thienopyrazine derivative represented by the formula, and a method for producing the same. [Rand Rare each independently a substituted or unsubstituted aryl group.]
