Electrochemically synthesised xanthone-cored conjugated polymers as materials for electrochromic windows

In this work, we present the electrochemical polymerisation process of triarylamine-xanthone derivatives and behaviour of the formed polymers using various potentiodynamic techniques. The formed electropolymers have limited conjugation but show very promising electrochromic behaviour. Furthermore, by coupling the electrochemical analysis with each polymer's spectroscopic output, we were able to evaluate doping processes and the type of charge carriers formed. Through careful analysis, we were able to describe the electropolymerisation process and formed triarylamine-based polyxanthone derivatives. The polymers were found to exhibit good stability and good colouration efficiency to suggesting that they have potential application in electrochromic devices.
