摘要
Poly(spiropyran)s were synthesized by polycondensation of a bis(indoline) monomer with bis(o-positioned formyl and hydroxy)-substituted aromatic monomers in alcoholic solvents. The structures of the products and their molecular weights were determined by the H-1 NMR and GPC measurements, respectively. Furthermore, photoisomerization behaviors of the poly(spiropyran)s were analyzed by the UV-Vis and H-1 NMR measurements of their solutions in dichloromethane upon the UV and visible light irradiations.
