Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>A stimuli‐responsive amphiphilic copolymer poly(NIPAM<italic>_m</italic>‐<italic>b</italic>‐VBNBI<italic>_n</italic>), including <italic>N</italic>‐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. © 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
