Research Abstract	There are no published accounts of photo-reversible metal-complexations that involve an insoluble spiropyran-carrying copolymer in aqueous solutions. Insoluble materials are attractive for metalion adsorption, such as adsorbents or sensors of metals, because of their relative ease of use. Herein, we describe the photoreversible Pb^<2+>-complexation for a synthetic spiropyran methacrylate (SPMA) in polar solvents (mixtures of methanol and water). Furthermore, we present the first demonstration of reversible photo-induced Pb^<2+>-complexation of an insoluble copolymer consisting of SPMA and perfluorooctylhydroxy methacrylate (FHMA), _6P(SPMA-FHMA) aqueous solutions.
