Abstract:

The post-chemiluminescence behavior of fifty three kinds of nitrogenous organic compounds was studied in the N-chlorosuccinimide-dichlorofluorescein system. Many substances were found to have the post-chemiluminescence activity in the system. After the analysis for the structure of these nitrogenous organic compounds, it was found that the state of the N atom in the molecules was important to the post-chemiluminescence activity and the post-chemiluminescence intensity of the nitrogenous organic compounds. The possible reaction mechanism of the post-chemiluminescence reaction was proposed based on the studies of the chemiluminescence kinetic characteristics, the chemiluminescence spectra and the fluorescence spectra of some related substances. The application value of these post-chemiluminescence reactions in analytical chemistry was estimated.

Key words: Post-chemiluminescence; N-Chlorosuccinimide; Dichlorofluorescein; Nitrogenous organic compound
