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

In this work, the synthesis and characterization of a new generation dithieno pyrrole derivative conjugated polymer, bearing alkoxy amine units is presented. The polymer showed multi electrochromism, low band gap and fast switching times in near IR region. The biosensor of glucose oxidase enzyme constructed with conjugated polymer shows high sensitivity, fast response, no significant reduction in signal, high stability and long term reproducibility by the retaining enzyme activity.170
