Conductive copolymer and a method of making thereof

A copolymer, comprising a polymerization product of:

• a first monomer represented by formula (I);
• and
• a second monomer represented by formula (II);
• wherein a mole ratio of the second monomer to the first monomer is from 1:2 to 1:4, and formulae (I) and (II) are:
• where X is sulfur, and Y is selenium;
• R1, R2, R3, R4, are independently a hydrogen, a hydroxy, a thiol, a fluoro, a chloro, a bromo, an iodo, a nitro, a cyano, an amino, a carboxy, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, an optionally substituted aryl, an optionally substituted alkanoyl, or an optionally substituted aroyl;
• and
• R5, R6, and each of R7 and R8 are independently a hydrogen, a fluoro, a chloro, a bromo, an iodo, a nitro, a cyano, a carboxy, an optionally substituted alkyl, an optionally substituted cycloalkyl, an optionally substituted arylalkyl, an optionally substituted aryl, an optionally substituted alkanoyl, or an optionally substituted aroyl.
