Conjugated polymers attracted great attention over the past two decades owing to their redox properties, flexibilities, adjustable band gaps and low cost. There are many applications of conjugated polymers such as electrochromic devices , smart windows , organic light emitting diodes , organic field effect transistors. Benzoselenadiazole, dihydroquinoxaline and thienothiophene are the units preferred in conducting polymers due to their electrochemical properties. There are no reports in the literature on polymers containing both moieties. With this motivation, we designed and decided to synthesize such a monomer. In this study, a novel benzoselenadiazole, dihydroquinoxaline and thienothiophene based monomer; 4-(3a,6a-dihydrothieno[3,2-b]thiophen-2-yl)-7-(thieno[3,2-b]thiophen-yl)benzo[c][1,2,5]selenadiazole (M1) and 2,3-bis(3,4-bis(decyloxy)phenyl)-5,8-dibromo-2,3-dihydroquinoxaline (M2) synthesized via Stille coupling and characterized in terms of their spectroelectrochemical and electrochemical properties. They can be good candidates for electrochromic devices in terms of their color and absorbtion. Especially the polymer 1 can be a great postulant for photovoltaic applications on account of its broad absorption .,
