Self-assembly of resorcin[4]arene-based coordination cages involving more than two resorcin[4]arenes poses significant challenges for the requirements of suitable functionalized resorcin[4]arene ligands and metals. Here, we report an unusual example of a metal-coordinated, resorcin[4]arene-based molecular trimer (1-NO), composed of three resorcin[4]arenes and three Cd(II) cations. In particular, 1-NO features efficient and selective removal of environmentally toxic dichromate (CrO) anions. Moreover, the Knoevenagel condensation reaction was also explored by using 1-NO as an efficient heterogeneous catalyst.
涉及两个以上间苯二酚[4]芳烃的基于间苯二酚[4]芳烃的配位笼的自组装，对合适的功能化间苯二酚[4]芳烃配体和金属的要求提出了重大挑战。在此，我们报道了一个不寻常的例子，即由三个间苯二酚[4]芳烃和三个Cd(II)阳离子组成的金属配位的、基于间苯二酚[4]芳烃的分子三聚体(1-NO)。特别地，1-NO具有高效且选择性地去除环境有毒重铬酸根(CrO)阴离子的特性。此外，还探索了以1-NO作为高效多相催化剂的Knoevenagel缩合反应。
