Four ionophores containing bipyridyl groups on a 7-deoxycholic amide derivative scaffold were designed and synthesized. Potentiometric evaluation of the Poly(vinyl chloride) (PVC) membranes containing those deoxycholic amides bearing bipyridyl moieties with a short linkage showed good affinity to silver(I) ion over alkali, alkaline earth and other transition metal cations. However, two bipyridyl groups flexibly linked to the deoxycholic frame through a long linkage do not result in appreciable potentiometric responses.
设计并合成了基于 7-去氧胆酰胺衍生物骨架的四种含有联吡啶基团的离子载体。含短连接基的联吡啶取代的去氧胆酰胺的聚氯乙烯（PVC）膜的电位评估表明，它们对银（I）离子具有良好的亲和性，超过了碱金属、碱土金属和其他过渡金属阳离子。然而，两个通过长连接基灵活连接到去氧胆酸骨架上的联吡啶基团并没有导致明显的电位响应。
