摘要

采用随机生成大三环产物的方法合成了吡啶双（羧酰胺）捆绑柱[5]芳烃胶囊。超分子胶囊的结构完整性由单个氮原子的特定取向决定，控制了受限结合腔的电子性质，促进了脂肪族有机客体与腈、异氰化物和胺官能团的长度选择性识别，这些官能团具有特殊的主客体结合亲和力和1,2-二氨基乙烷的选择性(Ka >；104 M-1)在极性有机溶剂中。

Single-Atom Tuning of Pyridine-Strapped Pillar[5]arene Capsules for Specific Guest Binding

Pyridine bis(carboxamide)-strapped pillar[5]arene capsules were synthesized with the serendipitous formation of macrotricyclic products. The structural integrity of the supramolecular capsules, determined by the specific orientation of a single nitrogen atom, controls the electronic properties of the confined binding cavity, facilitating length-selective recognition of aliphatic organic guests with nitrile, isocyanide, and amine functional groups with exceptional host–guest binding affinity and selectivity for 1,2-diaminoethane (K_a > 10⁴ M^–1) in a polar organic solvent.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
