摘要

Abstract 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.
