| Outline of Final Research Achievements |
Spiropyrans are known as a photo-reversible compound, which is able to form complexes with heavy-metal ions. In this research, we have prepared porous polymeric spiropyran hydrogels by polymerization under freezing solutions. The resulting porous materials had heterogeneous distribution of their pores indicating heterogineous freezing of the solvents. Next, we tried to freeze the solution containing the monomers momentarily, and then, obtained relatively homogeneous porous polymer compounds. Diffusion of several metal ions through the hydrogels of the porous spiropyran polymers was observed by measurement of color change of metal complexation of the spiropyran portion of the polymers.
