The development of selective electrochemical iron sensor is still a challenging task. One promising possibility is to use organically functionalized inorganic particles, for instance silica, as sensitive element. Herein, we report on the design and synthesis of calix[4]arene-based platforms modified with ICL670 iron chelator and alkylamino chain(s). These new molecular edifices could be easily grafted
选择性电化学铁传感器的开发仍然是一项艰巨的任务。一种有前途的可能性是使用有机官能化的无机颗粒,例如二氧化硅作为敏感元素。在本文中,我们报道了用ICL670铁螯合剂和烷基氨基链修饰的基于杯[4]芳烃的平台的设计和合成。这些新的分子结构可以很容易地接枝到二氧化硅颗粒上。该策略依赖于在下部边缘以部分圆锥或1,3-交替构型的烷基氨基链对选择性杯[4]芳烃进行官能化。提出并讨论了不同的合成路线。
