Halogen bonding and π–π interactions in the solid-state structure of a butadiynylene-linked bis(iodoperfluoroarene)
摘要:
本文讨论了一种丁二烯连接的双叉卤素键供体的固态结构,这种供体既可以是单一成分,也可以是与四正丁基碘化铵的共晶体。溶液相结合数据表明,这种只具有单构象自由度的供体通过收敛结合模式以 1:1 的配比与卤化物相互作用。与此相反,它在固态下与碘化物形成人字形链。通过 X 射线晶体学数据,可以详细研究伴随卤素键网络形成的分子结构和超分子组织的变化。

interactions of iodoperfluoroarenes and ‐alkanes with anions in organic solvent were studied. The data indicates that favorable halogen‐bonding interactions exist between halide anions and the monodentate model compounds C6F5I and C8F17I. These data served as a basis for the development of preorganized multidentate receptors capable of high‐affinity anion recognition. Several new receptor architectures were
研究了碘代氟代芳烃和烷烃与阴离子在有机溶剂中的相互作用。数据表明卤化物阴离子与单齿模型化合物C 6 F 5 I和C 8 F 17之间存在有利的卤素键相互作用I.这些数据为开发能够进行高亲和力阴离子识别的预组织多齿受体奠定了基础。准备了几种新的受体结构,并对初步通讯中描述的多齿碘全氟苯甲酸酯的设计进行了更详细的评估。计算被用来更好地解释这些研究中产生的构效关系。阴离子结合的热力学(通过van't Hoff分析)和溶剂效应的研究揭示了这些卤素键相互作用的细节。
