Abstract

A benzothiadiazole bearing donor-acceptor-donor (D-A-D) type monomer (M₃) was synthesized using the combination of 3, 4- ethylenedioxythiophene (EDOT) and thiophene donor units to understand the effect of donor strength on the optoelectronic and electrochemical properties. The resulting monomer was polymerized electrochemically (P₃) and compared with its symmetrical thiophene (P₁) and EDOT (P₂) bearing homologues whether there exists a combination of the electrochemical and optical characteristics. Also, copolymer studies were performed with symmetrical thiophene (M₁) and EDOT (M₂) containing monomers in order to compare the results with P₃. Cyclic voltammetry (CV) and spectroelectrochemistry results revealed that P₃ is a low band gap polymer (1.18 eV) having both p-and n-type property which is superior to the copolymers synthesized using M₁ and M₂.
