本文报道了8-甲氧基-4-甲基-2H-苯并[g]色烯-2-酮（1）的荧光性质。荧光团1在非质子溶剂（例如，荧光量子产率Phi（f）450 nm）在质子溶剂（例如，Phi（f）= 0.21，在甲醇中）。荧光团1在开发新的荧光（荧光“关-开”）传感器中也显示出良好的适用性。[结构：见正文]
The unusual fluorescence properties of 8-methoxy-4-methyl-2H-benzo[g]chromen-2-one (1) are described. The fluorophore 1 is almost nonfluorescent in aprotic solvent (e.g., fluorescence quantum yield Phi(f) 450 nm) in protic solvent (e.g., Phi(f) = 0.21 in methanol). The fluorophore 1 also shows good applicability in developing a new fluorogenic (fluorescent "off-on") sensor. [structure: see text]
