摘要： 本文采用荧光光谱和紫外-可见光谱的方法测定了单-[6-(氨基)-6-脱氧]-β-环糊精(NH2-β-CD)、单-[6-(乙二胺)-6-脱氧]-β-环糊精(EN-β-CD)、单-[6-(二乙烯三胺)-6-脱氧]-β-环糊精(ETA-β-CD)、单-[6-(三乙烯四胺)-6-脱氧]-β-环糊精(TETA-β-CD)在磷酸缓冲溶液(25?C, pH 7.2)和碳酸缓冲溶液(25?C, pH 10.5)中分别与几种阴离子表面活性剂，如辛烷基磺酸钠(OAS)、癸烷基磺酸钠(TDS)和十二烷基磺酸钠(SDS)，形成化学计量比为1:1的超分子配合物的稳定常数。结果表明，中性条件下，多胺环糊精键合三种表面活性剂客体的稳定常数可达2.6?102 ? 4.35?104 M-1，碱性条件下的键合能力则相对较弱。无论在碱性或中性条件下，主-客体键合能力都随客体分子中碳链的增长而增大。

Abstract: The binding constants between several polyamine-modified β-cyclodextrins, i.e. mono(6-amino-6-deoxy)-β-CD(NH2-β-CD), mono[6-(ethylenediamino)-6-deoxy]-β-yclodextrin(EN-β-CD), mono[6-(diethylenetriamino)-6-deoxy]-β-cyclodextrin(DETA-β-CD), mono[6-(triethylenetetraamino)- 6-deoxy]-β-cyclodextrin (TETA-β-CD) and three anionic surfactants (CnH2n+1SO3Na, n=8, 10, 12) in phosphate buffer solution (25?C, pH 7.2) and carbonic acid buffer solution (25?C, pH 10.5) were measured by the method of UV-Vis and fluorescence spectroscopy titration, in which all the hosts and guests formed 1:1 inclusion complexes. The obtained results show that the binding constants between polyamine-modified β-cyclodextrins and anion surfactants are in the region of 2.6?102 ? 4.35?104 M-1 in neutral condition, whereas in basic condition the binding would become weaker. In both of two pH conditions, the binding ability became much stronger with increasing the carbon number of anionic surfactants.
