摘要: A novel fluorescent reagent for hydroperoxides, 4-(2-diphenylphosphinoethylamino)-7-nitro-2,1,3-benzoxadiazole (1), was developed on the basis of method designing photoinduced electron transfer (PET) reagents having a benzofurazan skeleton. Compound 1 quantitatively reacted with hydroperoxides to give its derivative, 2. In acetonitrile, Phi value (0.44) 2 31 times greater than that 1. The long excitation (458 nm) and emission (520 wavelengths are suitable determination especially in biosamples. [structure: see text]
