چکیده انگلیسی
1,4-Bis(2-thienyl)-benzene monomer is successfully synthesized via coupling reaction. Poly(1,4-bis(2-thienyl)-benzene) (PBTB) is electrochemically synthesized and characterized. Resulting polymer film has distinct electrochromic properties. Its application in electrochromic devices (ECDs) is discussed. PBTB is switched between yellow in the neutral state and green in the oxidized state. Electrochromic switching of PBTB film is performed and the polymer film shows a maximum optical contrast (ÎT %) of 44.8% at 610Â nm in visible region with a response time of 1.6Â s. The coloration efficiency (CE) of PBTB is calculated to be 162Â cm2Â Câ1. Electrochromic device (ECD) based on PBTB and poly(3,4-ethylenedioxythiophene) (PEDOT) is also constructed and characterized. Maximum contrast (ÎT %) and switching time of the device are measured as 29.5% and 0.43Â s at 628Â nm. The CE of the device is calculated to be 408.9Â cm2Â Câ1. Clear change from green (at neutral state) to blue color (at full oxidized state) of this ECD is demonstrated with reasonable cycle life.
