Thiacalix[4]arene ionophores comprised of cyclic or linear O,S,N ligating and/or π-coordinate groups on the lower rim were synthesized and their Ag+ binding was studied by 1H NMR methods in comparison with the respective known and novel calix[4]arene counterparts. Calix[4](O,S,N)crowns were found stronger binders than the π-coordinate molecules and thiacalixarene ionophores were generally superior
合成了在下部边缘由环状或线性O,S,N连接和/或π坐标基团组成的Thiacalix [4]芳烃离子载体,并通过1 H NMR方法与各自已知的和新颖的相比,研究了它们的Ag +结合杯[4]芳烃同行。发现杯Calix [4](O,S,N)冠比π坐标分子更强的结合剂,而噻杯芳烃离子载体通常优于杯芳烃。这项研究有助于开发在亚纳摩尔级区域工作的银离子选择性电极。
