(Diagram presented) 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 Φf 450 nm) in protic solvent (e.g., Φf = 0.21 in methanol). The fluorophore 1 also shows good applicability in developing a new fluorogenic (fluorescent "off-on") sensor.

Fluorescent conjugates of N-benzyloxycarbonyl protected γ-aminobutyric acid were prepared by coupling to its C-terminus several polyheteroaromatic, based on the oxobenzopyran skeleton (trivially known as coumarin) and polyaromatic labels, such as naphthalene and pyrene. Photophysical properties were evaluated, as well as their behaviour towards photocleavage by irradiation in MeOH/HEPES buffer solution (80:20), in a photochemical reactor at different wavelengths (254, 300, 350 and 419 nm), followed by HPLC/UV monitoring.
