摘要
研究了β－环糊精（β－ＣＤ）及其衍生物（２－羟基）丙基－β－环糊精（ＨＰ－β－ＣＤ）、叔胺－β－环糊精（ＴＡ－β－ＣＤ）对萘胺荧光强度的影响，发现ＨＰ－β－ＣＤ、ＴＡ－β－ＣＤ对萘胺的荧光增强作用比β－ＣＤ大。初步探讨了十二烷基硫酸钠（ＳＤＳ）、Ｔｒｉｔｏｎ Ｘ－１００、溴化十六烷基三甲铵（ＣＴＭＡＢ）与β－ＣＤ或 ＨＰ－β－ＣＤ对萘胺荧光强度的协同增敏作用及其机理。
Effect of β-cyclodextrin and its derivatives such as 2-hydroxypropyl-β-cyclodex- trin (HP-β-CD), tertiary amine β-cyclodextrin (TA-β-CD) on the fluorescence intensities of α-,β-naphthylamine were investigated in detail. The mechanism of the fluorescence enhance- ment of β-CD and its derivatives on naphthylamine was discussed based on the inclusion con- stants. The synergistic fluorescence enhancements of β-CD or its derivatives with surfactants such as SDS, Triton X-l00 and CTMAB were also studied.
