Novel hydrophobic monomer N ‐(1‐pyrenebutyryl)– N ′‐methacryloyl hydrazide (PyMAHy) was synthesized and copolymerized with N ‐vinylpyrrolidone (NVP) to get a series of amphiphilic copolymers. FTIR, 1 H NMR, TEM, gel permeation chromatography–multi‐angle laser light scattering, UV–vis spectroscopy, and fluorescence spectroscopy were used to characterize these polymers. Results of fluorescence measurements show that these copolymers have good recognition ability to CO 3 2− anion and the fluorescence emission intensity was quenched linearly upon the addition of CO 3 2− anion. The recognition for CO 3 2− anion was also proved by the results of TEM for the significantly difference in the morphology of copolymer before and after adding CO 3 2− anion into copolymer Tris–HCl buffer solution. Results suggest the potential of these amphiphilic copolymers as fluorogenic chemosensor materials. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 2371–2376, 2006
