利用圆二色光谱法研究对比了有机溶剂-水混合溶液、纯水及两种高离子浓度溶液中,3种修饰的β-环糊精衍生物的构型及对环辛烯客体分子的包结现象及溶液环境对主客体相互作用的影响,探讨了β-环糊精衍生物在高离子浓度溶液环境中的分子识别能力。结果表明,与有机溶剂-水混合溶液相比,β-环糊精衍生物与客体分子在高离子浓度溶液中仍保持了较高的包结稳定常数,为进一步拓展环糊精在高离子浓度溶液环境中的应用提供了基础。 The circular dichroism spectroscopy was used to study the conformations of three modified β-cyclodextrin derivatives in organic solvent-water mixed solution, pure water and two kinds of high-ion concentration solutions, And the effect of solution environment on the interaction between host and guest, the molecular recognition ability of β-cyclodextrin derivatives in high ionic strength solution environment was discussed. The results show that β-cyclodextrin derivatives and guest molecules still maintain higher inclusion stability constants in high ionic strength solution than organic solvent-water mixed solution. In order to further expand the cyclodextrin in high ion concentration The application of solution environment provides the basis.
