Abstract

Up to date there are few studies reporting the use of selenophene derivatives as electrochromic polymers. This report highlights the synthesis of a selenophene containing multi-ring aromatic polymer which possesses reasonable optical contrasts at both visible and near-IR regions. Electrochemical synthesis of a conducting polymer from a multi-ring aromatic monomer, 2-(2,5-bis(hexyloxy)-4-(selenophen-2-yl)phenyl)selenophene (BSB(OC6H13)(2)), was achieved at a lower potential than its corresponding parent, selenophene. The strong absorption band for the undoped polymer was 474 run and the onset energy for the pi-pi transition (Eg) was 1.9 eV (645 nm).
