N ‐Butyl‐ N ′‐dansylthiourea as Fluorescent Broad‐Band Complexing Agent N ‐Butyl‐ N ′‐dansylthiourea ( 2 ) [dansyl = 5‐(dimethylamino)‐1‐naphthylsulfonyl] is obtained by the reaction of dansylamide ( 1 ) with butyl isothiocyanate. The compound is a stable, fluorescent complex agent for a broad spectrum of metal ions. The UV spectra and fluorescence of the ligand and some metal complexes are discussed. The fluorescence of the dansyl group is strongly affected by metal ions.
