室温磷光光度法(RTP)在生命科学、环境科学、药物及临床等领域越来越显示出广阔的应用前景。为提高磷光信号和分析灵敏度,重原子微扰剂(HAP)通常是必要的实验条件之一。在环糊精诱导室温磷光(CD-RTP)中溴代烷烃是常用的HAP。然而,本文研究表明在没有任何HAP的环糊精体系加入少量环已烷(CH)也能诱导出一些多环芳烃及氮杂环化合物的RTP。而且在没有除氧的条件下也能产生RTP。本文对这一新的磷光现象进行了详细的研究。
Room temperature phosphorescence spectrometry (RTP) has shown more and more promising applications in the fields of life science, environmental science, medicine and clinic. Heavy atom perturbation agent (HAP) is usually one of the necessary experimental conditions to improve the phosphorescence signal and the analytical sensitivity. Brominated alkanes are the most commonly used HAP in cyclodextrin-induced room temperature phosphorescence (CD-RTP). However, the present study shows that addition of a small amount of cyclohexane (CH) to cyclodextrins without any HAP can induce some RTPs of PAHs and azacyclic compounds. And in the absence of oxygen can also produce RTP. This article has carried on the detailed research to this new phosphorescence phenomenon.
