摘要
循环化学发光是一种新颖的方法,随着其实验研究的不断成功,已经展示出许多意想不到的用途,但其理论研究还有待于突破。该文以鲁米诺体系为基础,结合钴的手性配合物增敏技术和单电子传递反应机理假设,展开了理论推演,获得了含义较为明确、经得起一些文献数据检验的循环化学发光理论公式;此外还推导出了若干与文献推测不甚相同但也能与一些实验数据相吻合的公式。根据所得公式,还能推演出循环化学发光的一些新测试方法,这将有助于该方法的深入研究和推广应用。
Cyclic chemiluminescence is a novel method.With a continuous success in experimental research,this method has been showing many unexpected applications,but its theoretical research is still waiting for breakthrough.Herein presented is the theoretical deduction on the cyclic chemiluminescence of luminol system sensitized by cobalt chiral complexes,based on the reaction mechanism of single electron transfer.The resulting theoretical formulas could stand the test of some literature data,which are able to figure out the theoretical meaning of the data.In addition,some of the theoretical formulas were also derived that were not very compatible with the literature speculation but could stand the test of some experimental data presently available.According to the obtained formulas,it is also able to deduce some new detection methods of cyclic chemiluminescence.This may contribute to the further researches and applications of this method.
