    • PROBLEM TO BE SOLVED: To provide a polymer material having function capable of capturing and detecting metallic ions, and to provide an element that uses the same. SOLUTION: This metallic ion sensing annular polymer material 100, containing imine and a benzene ring detects electrochemically the metallic ions of a microamount, by measuring the redox potential of the polymer material due to coordination (formation of complex) of the metal ion with the imine. The polymer material is formed into a square, as shown in structure 110, in a repetition unit n=2, where symbol Z represents cis-type imine. The polymer material is formed into a triangle, as shown in structure 120, in the repetition unit n=3, where symbol E represents the trans-type imine. The structure 120 is a mixture, that has the cis-type imine and trans-type imine mixed at 1:1 ratio. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供具有能够捕获和检测金属离子的功能的聚合物材料,并提供使用该金属离子的元素。 解决方案:通过测量由于金属离子的配位(形成复合物)而导致的聚合物材料的氧化还原电位,含有亚胺和苯环的金属离子感测环状聚合物材料100电化学地检测微量的金属离子 与亚胺。 如结构110所示,聚合物材料在重复单元n = 2中形成正方形,其中符号Z表示顺式亚胺。 聚合物材料在重复单元n = 3中形成为如结构120所示的三角形,其中符号E表示反式亚胺。 结构120是具有按1:1比例混合的顺式亚胺和反式亚胺的混合物。 版权所有(C)2007,JPO&INPIT
