摘要: 报道了水溶液中主体2,3,6-三甲氧基β-环糊精与客体氢酸及甲酚异构体包结作用的核磁共振研究结果.研究表明,四种不同的取代苯酚均能进入主体的疏水腔中发生包结作用;根据主体甲氧基质子化学位移的变化值随不同主客体浓度的变化关系计算出水溶液中主体和不同客体间包结作用的平衡常数.

Abstract: In this paper we report on the result of study on aqueous solution of inclusion-complexesof host 2, 3, 6-tri-O-methylated β-Cyclodextrin with guest hydroquinone and cresols by 1HNMR spectroscopy. The study shows that every four different substituted phenol can bebond by the host through inserting into the host hydrophobic cavity, and the correspondingbinding constant in aqueous solution can be calculated according to the relation betweenchemical shift changes of the host methoxyl protons and the concentration changing of thehost and different guests.

Key words: 2,3,6-tri-O-methylated β-Cyclodextrin, Hydroquinone, Cresols, 1H NMR, Inclusion-complexion, Binding constant
