the preparation of a [2]rotaxane. Removal of the discrete nitrate anion template from the [2]rotaxane reveals an interlocked host system capable of strong and selective recognition of nitrate, in aqueous-organic solvent mixtures, over a range of more basic mono-charged oxoanions.
通过制备[2]轮烷,证明了分子结构互锁的第一个硝酸根阴离子模板组装体。从[2]轮烷中除去离散的硝酸盐阴离子模板,揭示了一个互锁的宿主系统,该系统能够在多种有机单电荷含氧阴离子上,在水-有机溶剂混合物中强而有选择性地识别硝酸盐。
