Binding properties of native alpha- and beta-cyclodextrin towards some nitrobenzene derivatives have been studied by means of UV-vis spectrophotometry. The former host is able to form complexes having 1:1 and 1:2 stoichiometric ratios with these guests, while only 1:1 complexes are detected with the latter host. A careful analysis of the thermodynamic parameters for complexation equilibria, under the perspective of the enthalpy-entropy compensation effect, reveals that binding abilities of the two different hosts are subject to different features.
通过紫外可见分光光度法研究了天然α-和β-环糊精对一些硝基苯衍生物的结合特性。前一种主体能够与这些客体形成化学计量比为1:1和1:2的配合物，而后一种主体仅检测到1:1的配合物。从焓-熵补偿效应的角度对络合平衡的热力学参数进行仔细分析，结果表明两种不同主体的结合能力具有不同的特征。
