Synthesis and characterization of a new poly (dithieno (3, 2-b: 2′, 3′-d) pyrrole) derivative conjugated polymer: Its electrochromic and biosensing applications

Synthesis and electropolymerization of a new conjugated dithieno(3,2-b:20,30-d) pyrole (DTP) derivative, namely, 2-(2-(2-(4H-dithieno[3,2-b:20,30-d]pyrrol-4-yl)ethoxy)ethoxy)ethanamine, (DTP-alkoxy-NH2) monomer are presented. The electrochemical, spectroelectrochemical effects and biosensor capability towards to glucose oxidase enzyme of P(DTP-alkoxy-NH2) polymer fi lm are investigated in detail during the placement of alkoxy-NH2 functional unit in the polymer. Electrochemical and optical results between neutral and oxidized states of the polymer fi lm show that (P(DTP-alkoxy-NH2)) has reversibly multi-electrochromic behaviors. Furthermore, glucose oxidase enzyme (GOx) is covalently immobilized on Au electrodes modi fi ed with P(DTP-alkoxy-NH2) conducting polymer. This enzyme is entrapped into con-ducting polymer during electropolymerization of DTP monomer on the electrodes. Some characterization parameters (Maximum reaction rate, MichaeliseMenten constants, temperature, pH and operational stabilities) for this kind of biosensor application is also determined.
