WebApr 30, 2024 · We have developed 7-diethylaminocoumarin-based chromophores that photoisomerize with visible light. These photoswitches possess many desirable attributes, including large extinction coefficients (18 600–59 100 M −1 cm −1), high quantum yields (0.45–0.50) and resistance to photofatigue.Additionally, time-resolved spectroscopy … WebPhotochromic diarylethenes represent one of the most important classes of molecular switches, and their fatigue resistance is reported in several papers. Previous studies have demonstrated that the presence of perfluorocyclopentene and methyl in the 4-positions of dithienylethenes improve the switching resistance. However, general guidelines to …
