Linear sugar‐derived oligo(amide‐triazole)s with one (dimer) to four (pentamer) carbohydrate and triazole units act as halide receptors. The binding affinities for the tetramers and pentamers follow the order Cl– > Br– > I–. The pentamer adopts a helix conformation, slightly distorted by chloride. The active site in the pentamer backbone involves the triazole‐CH, amide‐NH, and H‐4′ from the carbohydrate
线性糖衍生的低聚(酰胺三唑)具有一个(二聚体)至四个(戊二烯)碳水化合物和三唑单元,可作为卤化物受体。四聚体和五聚体的结合亲和力遵循Cl – > Br – > I –的顺序。五聚体采用螺旋构象,略微受氯化物扭曲。五聚体骨架中的活性位点涉及碳水化合物残基中的三唑-CH,酰胺-NH和H-4'。
