一些含氮有机物在N-氯代丁二酰亚胺-二氯荧光素体系中的后化学发光反应

Post-chemluminescence Reaction of Some Nitrogenous Organic Compounds in the N-Chlorosuccinimide-dichlorofluorescein System

研究了53种含氮有机物在N-氯代丁二酰亚胺(NCS)-二氯荧光素体系中的后化学发光行为,结果发现,很多物质在NCS-二氯荧光素体系中都具有后化学发光活性.经过结构分析发现,这类物质有无后化学发光活性以及后化学发光活性的强弱主要与其分子结构中N原子的状态有关.在对有关反应的动力学性质、化学发光光谱及有关物质荧光光谱的研究基础上,提出了这类后化学发光反应的可能机理.

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 postchemiluminescence 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.
