of substituents to the guest phenyl group further stabilises the complex by an additional factor of up to 1000. When a nitro substituent is present on the guest phenyl group, the complex has a sub-picomolar dissociation constant (370 fM). The remarkable substituenteffects observed in water for these complexes can be rationalised by comparison with the magnitude of the corresponding substituent effects
水中的分子识别涉及极性官能团相互作用、极性和非极性表面的部分去溶剂化以及构象灵活性的变化,这对超分子行为的合理设计和解释提出了挑战。构象明确的超分子复合物可以在水和非极性溶剂中进行研究,为解开这些贡献提供了一个平台。这里,四种不同的杯[4]吡咯受体和十三种不同的吡啶N-氧化物客体之间形成的1:1复合物已被用来剖析控制取代基对水中芳香相互作用的影响的因素。受体吡咯供体和客体N之间的氢键相互作用配合物一端的氧化物受体锁定配合物另一端芳香族相互作用簇的几何排列,使得客体上的苯基与四个芳香族产生两个边对面和两个堆叠相互作用受体的侧壁。这些芳香相互作用对复合物整体稳定性的热力学贡献通过化学双突变体循环使用等温滴定量热法和11 H NMR竞争实验。受体和客体上的苯基之间的芳香族相互作用使复合物稳定了 1000 倍,并且向客体苯基添加取代基进一步使复合物稳定了高达 1000 倍的额外系数。当硝基取代基存
