POLY[3-(ALKYL)THIOPHENE] DERIVATIVES AS PROMISING MATERIALS FOR ASSEMBLING AN ELECTROCHROMIC DEVICE

3-[ω-(p-methoxyphenoxy)alkyl] thiophenes were synthesized and electrochemically polymerized on ITO/glass electrodes by the potentiostatic method. Short alkyl chains substituted thiophene derivatives are generally difficult to polymerize by electrochemical methods, however, potentiostatic de...
