Multi-functional copolymers based on NIPAM and thienoviologens with different numbers of thiophene units (n = 1, 2 and 3) were synthesized and their absorption/emission properties were systematically studied. This discovery successfully integrated thermo-responsive, electrochromic, electrofluorochromic and photodynamic antimicrobial properties into one system and will be greatly beneficial to expand the potential applications of viologen derivatives.
