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-NO₃), composed of three resorcin[4]arenes and three Cd(II) cations. In particular, 1-NO₃ features efficient and selective removal of environmentally toxic dichromate (Cr₂O₇^2–) anions. Moreover, the Knoevenagel condensation reaction was also explored by using 1-NO₃ as an efficient heterogeneous catalyst.

金属组装的，以间苯二酚[4]芳烃为基础的分子三聚体，用于有效去除有毒重铬酸盐污染物和Knoevenagel缩合反应

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]芳烃配体和金属的需求提出了重大挑战。在这里，我们报告一个不寻常的例子，它是由三个间苯二酚[4]芳烃和三个Cd（II）阳离子组成的金属配位的间苯二酚[4]芳烃基分子三聚体（1-NO ₃）。尤其是1-NO ₃具有高效和选择性去除对环境有毒的重铬酸根（Cr ₂ O ₇^2-）阴离子的功能。此外，还通过使用1-NO ₃作为有效的多相催化剂探索了Knoevenagel缩合反应。
