Tweezer-type ionophores containing C3-bipyridyl and C12-dithiocarbamoyl groups, or C3-bithiophenyl with C12-dithiocarbamoyl groups on a 7-deoxycholic amide or cholane derivatives were designed and synthesized. Potentiometric evaluation of the PVC membranes containing those deoxycholic amides/cholanes linked with unsymmetrically substituted tweezer-type bipyridyl or bithiophenyl with dithiocarbamoyl
设计并合成了含有C3-联吡啶基和C12-二硫代氨基甲酰基或在7-脱氧胆酰胺或胆烷衍生物上具有C12-二硫代氨基甲酰基的C3-联硫苯基的镊子型离子载体。含有与二硫代氨基甲酰基部分不对称取代的镊子型联吡啶或联硫苯基连接的那些脱氧胆酸酰胺/胆烷的PVC膜的电位测量评估证明了它们对银(I)离子的良好亲和性和选择性。尤其是,在cholan-24-amide或胆烷的3α-位具有联硫基苯基部分且在12α-位具有二苯基氨基硫代甲基甲硫基乙酰氧基的离子载体显示出最优异的结果,其理论斜率值为59 mV /十倍。
