Kinetics of thermal decoloration of a photomerocyanine in mixtures of protic and nonpolar solvents

The kinetics of thermal conversion of a photogenerated merocyanine into its more stable spiropyrane form was studied in mixtures of ethanol with nonpolar solvents, toluene, n-hexane or CO2. For solutions of ethanol concentration higher than ca. 1.5 M two decay rates are observable. Below that concen...
