β-萘甲酰化β-环糊精的分子识别性能研究

最近二十年,外形似“锥简”,腔内疏水,脏外亲水的环糊精（Cyclodextrin,CD包括a,o,7－CD等）,以其特有的结构在模拟酶、分子识别等众多领域内深受广大科学工作者重视［’－‘］．为了获得更有效的模拟酶及分子识别功能体,我们已合成并报道了一系列含有发色基团的CD衍生物卜一句．本文利用基紫外光谱对产一茶甲酸化公CD的分子识别性能作了研究,结果显示3一位修饰CD（3一氧一八茶甲酸基一只CD）1对客体（环己醇）的包结性能是6一位修饰CD（6一氧一界禁甲酸基一八CD）2的4．4倍·结果还显示用环乙烷作客体时与主体正的包结和用…

Studies for the Molecular Recognition Abilities of β-Naphthoated β-Cyclodextrin(β-CD) Derivatives

The molecular recognition abilities of β-naphthoated β-CD derivatives as the host compounds were studied: 3-o-β-Naphthoyl-β-CD has a largely improved association constant with cyclohexanol than the corresponding 6-position substituted β-CD derivative has. On the other hand, the polarisablity and the sturcture of the gueset molecule are also important factors which affect the association constant. Cyclohexane may form the 1:2 type inclusion compound with the host compound in this report.
