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.

electron transfer compound 2, our previously published donor−bridge−acceptor system (anthracene−CH2−bithiophene−pyridinium) is modified by incorporation of the photoisomerizable dithienylethene (DTE) as a switching unit. In the open-ring form 2a, excitation of the anthracene donor leads to an intramolecular chargeseparation proved by identification of the anthracene radical cation in transient absorption
