Description
  • Eight ?uorescent compounds containing a naphthotriazole moiety substituted at position 2 by a (vinylsulfonyl)aryl group or its precursors, containing either a hydroxyl or sulphonic acid groups or N-methylglycine, were prepared and characterized. The products were recovered in moderate yield after column chromatography or recrystallization and identi?ed using 1H and 13C NMR; double resonance, heteronuclear multiple quantum coherence and heteronuclear multiple bond correlation experiments were carried out for complete assignment of proton and carbon signals. Absorption and emission spectra were obtained, in acetonitrile and ?uorescence quantum yield determined. All compounds offer promise as ?uorescent probes owing to their high ?uorescence quantum yield.
