A stimuli-responsive amphiphilic copolymer poly(NIPAM(m)-b-VBNBIn), including N-isopropylacrylamide (NIPAM) as a thermoresponsive unit and 1-(4-vinyl benzyl)-2-naphthyl-benzimidazole (VBNBI) as a sensitive fluorophore unit, was designed and synthesized by reversible addition-fragmentation chain transfer polymerization. The aqueous solutions of the copolymers exhibited reversible fluorescent response to pH and temperature. In addition, the copolymers showed aggregation-induced fluorescence enhancement in THF/water mixture. (c) 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2013, 51, 4459-4466
