Unimolecular ion channels were designed by functionalization of a new type of cyclic oligosaccharides, cyclo-oligo-(1 â 6)-β-D-glucosamines, with pentabutylene glycol chains. Their ion transporting activity was tuned by varying oligomericity. A halide selectivity sequence, Clâ > Brâ > Iâ was observed.
单分子离子通道是通过功能化一种新型环状
寡糖——环状寡(1 â 6)-β-
D-葡萄糖胺,与戊基
丁二醇链设计的。它们的离子传输活性通过改变寡聚度进行了调节。观察到
氯离子选择性序列为 Clâ > Brâ > Iâ。
