Abstract

1-(4-Fluorophenyl)-2,5-di(thiophen-2-yl)-1H-pyrrole (FPTP) was synthesized and polymerized both chemically and electrochemically. Spectroelectrochemistry experiments reflected a pi to pi* transition with a band gap energy of 1.94eV for the polymer. A dual type electrochromic device (ECD) of P(FPTP) and poly(3,4-ethylenedioxythiophene) (PEDOT) was constructed. The device switches between yellow and blue upon application of -0.8 V and +1.1 V, respectively. Optical contrast was calculated as 19.4% whereas switching time was found as 1.4s at maximum contrast point. (c) 2007 Elsevier B.V.. All rights reserved.
