✦ Synopsis


Photoselection in thermoreversible photochemical reactions was theoretically and experimentally considered using the photoisomerization of 9-tert-butylanthracene in polystyrene as a model system. The influence of the thermal rotational mobility of the reactive molecules on the photoselection is discussed. A satisfactory agreement between the theoretically calculated kinetics of photoisomerization and the accumulation of dichroism and the experimental results is obtained. It is demonstrated that photo-oxidation in a polymer matrix corrupts the photoselection process.
