摘要：

The kinetics of photocoloration of spiropyrans in the presence of a metal ion in solution was studied using laser kinetic spectroscopy. Mathematical simulation of the photocoloration process, semiempirical quantum-chemical calculation, and comparison of their results with experimental data have provided evidence that several trans-isomers of the merocyanine form of spiropyrans can take part in the complex formation reaction. An experimental procedure for determining the involvement of one, or two, or more trans-isomers of spiropyrans in the complexation reaction in the course of photoinduced opening of the pyran cycle and the formation of a stable trans-isomer was proposed. The scheme of the photoreaction is given.
