用移动猝灭剂（碘离子，间二氰苯）和不移动猝灭剂（n -甲基- n -癸苯胺，氯化十四烷基吡啶）猝灭1-甲基芘（1-MePy）荧光，研究了十六烷基三甲基氯化铵（CTAC），十四烷基三甲基氯化铵（TTAC）和十二烷基三甲基氯化铵（DTAC）的水胶束体系。荧光猝灭可以测定聚集数，这是胶束的重要参数之一。本研究评估了结构因素（链长，头基团）和环境因素（洗涤剂浓度，如添加电解质，温度和反离子）对胶束的影响。
The quenching of the 1-methylpyrene (1-MePy) fluorescence by mobile (iodide ion, m-dicyanobenzene) as well as immobile (N-methyl-N-decylaniline, tetradecylpyridinium chloride) quenchers has been used to study the aqueous micellar systems of cetyltrimethylammonium chloride (CTAC), tetradecyltrimethylammonium chloride (TTAC), and dodecyltrimethylammonium chloride (DTAC). Fluorescence quenching allows the determination of the aggregation number, as one of the important parameters of the micelle. This study evaluates thé influence ofstructural factors (chain length, headgroup) as well as environmental factors (detergent concentration such as addition of electrolyte, temperature, and counterion) on micellization.
