                                    The macrocyclic polyether -amide (1) is shown to be mere selective than its corresponding monocyclic analogue (4) for the Ca2+ ion; the potentiometric selectivity for Ca2+ relative to Mg2+ is improved by more than one order of magnitude.
                                    大环聚醚-酰胺(1)仅比其相应的单环类似物(4)对Ca 2+离子具有选择性;Ca 2+相对于Mg 2+的电位选择性提高了一个数量级以上。
