A spectral and kinetic study was carried out of some substituted 1,2-dithienylperfluorocyclopentenes and 1,2-bis(benzo[b]thienyl)perfluorocyclopentenes suitable for use as photosensitive components of photochromic recording media for optical memory. The introduction of nitro groups into the benzothienyl moieties dramatically decreases photodegradation and increases the fatigue resistance of these photochromes.

Spectral-kinetic characteristics of a number of new photochromic dihetaryethenes with different five-membered cyclic bridges are measured and discussed. It was shown that these characteristics depend on a bridge structure as well as a nature of substituents in the thienyl fragments.
