“…With another intriguing aspect, the film thickness and morphology can be easily tuned by controlling the electrochemical parameters (potential, current, and deposition time), which is of great importance whenever surface coating is concerned [13]. In addition, oxidative and reductive doping to the conductive form can be achieved in situ electrochemically, allowing these polymers to be easily switched from the conductive to insulating state.Though it has been well known that both transition metal terpyridine (TPY) complexes with functional groups [14][15][16][17] and arylamines [18][19][20] are excellent electroactive materials for preparing optical/electronic ultrathin films, electropolymerization of the hybrid polymer incorporated of electron-deficient Ru(II)-TPY complex directly into the π-conjugated triphenylamine-based polymer backbone has so far never been reported yet. In this paper, the electro-active triphenylamine moiety was introduced at 4-position of TPY to form the functionalized Ru(II) complex, and its oxidative electropolymerization behaviour and the spectroscopic, electrochemical and spectroelectrochemical properties of as-formed D-A polymer were investigated.…”
