Paper Abstract

We report on room-temperature photochromism of Zn- tetrabenzoporphyrine-doped polymethylmethacrylate. A one- quantum, thermo-reversible photoreaction is initiated with the 633 nm line of a HeNe-laser. The quantum yield depends strongly on the concentration of an electron acceptor which is doped into the matrix. The optical density of the sample can be reduced by up to a factor of 5 via irradiation, leading to refractive index changes of about 0.015.
