containing 3, 4 and 6 as neutral ionophores in a PVC membrane were prepared and their selectivity coefficients for Ag+ (KpotAg,M) were investigated against other alkali metal, alkaline-earth metal, lead, ammonium ions and some transition metal ions using the mixed-solution method. These ISEs showed excellent Ag+ selectivity towards most of the interfering cations examined, except for Hg2+ which has a relativly
25,27-双(6-羟甲基-2-吡啶基甲氧基)-26,28-二丙氧基杯[4]芳烃3及其衍生物4 和25,27-双(6-二苯基膦甲基吡啶基甲氧基)-26,28-二丙氧基-5,11 ,17,23 -四-叔-butylcalix [4]芳烃6已被合成和表征通过1个H NMR光谱和元素分析。获得了4的X射线晶体结构,并显示了通过分子间氢键和固态的桥连甲醇分子的无限片状聚集体。离子选择性电极(ISE)对银+含3,4和6 制备PVC膜中性离子载体,并采用混合溶液法研究了其对其他碱金属,碱土金属,铅,铵离子和某些过渡金属离子的Ag +(K pot Ag,M)选择性系数。这些ISE对所检查的大多数干扰阳离子均表现出极佳的Ag +选择性,但Hg 2+的干扰相对较低(log K pot Ag, M≤ - 1.5)。
