CHEMILUMINESCENT CHARACTERISTICS OF SOME INDOLE-DERIVATIVES

The chemiluminescent behaviour of some indole derivatives in alkaline solution in the presence of Fe3+ was studied in detail. The effects of various kinds of surfactants and oxidants on the chemiluminescent rea ction were studied. A how injection system with chemiluminescent detec tion was developed for the determination of tryptophan, and the effect s of some inorganic ions and basic amino acids were examined, Based on the results of treatment with the Huckel molecular orbital method and the investigations of fluorescent and absorption spectra, the relatio nship between structural characteristics and chemiluminescent behaviou r is discussed, and a possible mechanism for this chemiluminescent rea ction is proposed.
