Photo-reversible Pb2+-complexation of thermosensitive poly(N-isopropyl acrylamide-co-spiropyran acrylate) in water

Photo-reversible Pb2+-complexation in a purely aqueous environment exhibiting a thermosensitive phase transition at a lower critical solution temperature was achieved using a synthetic copolymer composed of N-isopropyl acrylamide and spiropyran acrylate.
