Coumarin-diene photoswitches for rapid and efficient isomerization with visible light?
Chemical Communications Pub Date: 2018-04-30 DOI: 10.1039/C8CC01091A
Abstract
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 indicates that both isomerization reactions are complete in less than 1 ns.
