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.
对一些取代的1,2-二噻吩全氟环戊烯和1,2-双(苯并[b]噻吩)全氟环戊烯进行了光谱和动力学研究,这些化合物适合用作光学存储照片chromic记录介质的光敏组件。将硝基引入苯并噻吩基团显著降低了光降解,并提高了这些光变色材料的疲劳耐受性。
