7-Hydroxy-4-(trifluoromethyl)coumarin (CAS number 575-03-1), derived from coumarin, is a pyrone fused benzene heterocyclic compound with a hydroxy group at 7-position and a trifluoromethyl substituent at 4-position. By having the electron delocalized core, 7-Hydroxy-4-(trifluoromethyl)coumarin is widely used as dyes and emitters in dye-sensitized solar cells (DSSCs) and OLEDs. 7-Hydroxy-4-(trifluoromethyl)coumarin has a strong binding affinity with H2S/HS−. The fluorescence intensity of 7-hydroxy-4-(trifluoromethyl)coumarin increases after the binding activity, which makes it a chemical sensor for detecting H2S/HS−. The photosensitivity of 7-hydroxy-4-(trifluoromethyl)coumarin is not limited to a specific chemical, but also related to the medium microviscosity and polarity. It allows 7-hydroxy-4-(trifluoromethyl)coumarin to be uses in monitoring chemical reactions such as polymerization.
