The thermodynamics of binding between native α- and β-cyclodextrin towards several p-nitro-aniline derivatives was examined, in order to gain further insights about the occurrence of different interaction modes for the two hosts. Valuable information was achieved regarding the ‘expanded hydrophobic sphere’ of α-cyclodextrin. Furthermore, very interesting and unexpected aspects of the behavior of β-cyclodextrin
研究了天然α-和β-环糊精与几种对硝基苯胺衍生物结合的热力学,以进一步了解两种宿主不同相互作用模式的发生。获得了有关α-环糊精“扩展疏水球”的宝贵信息。此外,β-环糊精的行为非常有趣和出乎意料的方面也得到了启发,例如氢键相互作用所起的关键作用。在“焓-熵补偿效应”的角度检查了实验数据,并讨论了有关该主题的一些想法。
