receptors have several important applications in sensing, separation and transport of negatively charged species. Amongst these receptors, di-zinc(ii) complexes are of particular interest for the recognition of oxoanions, in particular phosphate derivatives. Herein we report the synthesis of a di-zinc(ii) receptor and show that it has high affinity and selectivity for bisphosphonates such as alendronate
金属基阴离子受体在带负电物质的感测,分离和运输中具有多个重要应用。在这些受体中,二锌(ii)配合物对于识别含氧阴离子,特别是磷酸酯衍生物特别感兴趣。本文中,我们报告了di-zinc(ii)受体的合成,并表明它对双膦酸盐(如阿仑膦酸盐和依替膦酸盐)具有很高的亲和力和选择性-这些双膦酸盐用于治疗许多骨骼疾病并显示出令人感兴趣的抗癌特性。通过单晶X射线晶体学已明确地建立了二锌(ii)受体与阿仑膦酸盐和依替膦酸盐的结合模式。另外,通过修饰受体的骨架,
