Abstract: The novel functionalised oxygen heterocycle 4-(hydroxymethyl)-6-methoxy-2-oxo-2H-benzo[h]benzopyran was synthesised and used in the preparation of a fluorescent ß-alanine conjugate. In order to evaluate its photosensitivity, photocleavage reaction in methanol/HEPES buffer (80:20) solution at different wavelengths of irradiation (250, 300 and 350 nm) was carried out and photocleavage kinetic data were obtained.
