title: Zinc-tetrabenzoporphyrine-doped poly(methyl methacrylate): a new photochromic recording medium.
abstract: A photochromic reaction in Zn-tetrabenzoporphyrine-doped poly(methyl methacrylate) was investigated at room temperature. A one-quantum thermoreversible photoreaction could be initiated in the sample with 633-nm He-Ne laser irradiation. The photoreaction quantum yield depended strongly on the concentration of an additional electron acceptor. The changes of the refractive index were also measured.
