An artificial selective K channel is formed from the supramolecular organization on bis(benzo-15-crown-5- ether-ureido)-pillar[5]arene compound. This channel achieves a selectivity of S = 5 for an initial transport rate of k = 3.2 × 10 s. The cation-file diffusion occurs via selective macrocyclic-filters anchored on inactive supporting pillar[5]arene relays. The sandwich-type binding geometry of the K cation by two 15-crown-5 moieties sites is a key feature influencing channel efficiency.
一种人工选择的 K 通道是由双（苯并-15-冠-5-醚脲基）-柱[5]芳烃化合物的超分子组织形成的。该通道对初始传输速率 k = 3.2 × 10 s 时实现了 S = 5 的选择性。阳离子文件通过锚定在非活性支撑柱[5]芳烃继电器上的选择性大环过滤器进行扩散。两个 15-冠-5 部分位点对 K 阳离子的三明治式结合几何形状是影响通道效率的关键特征。
