A series of multinuclear lanthanide-covalent organic polyhedra (LnCOPs), including pillar-typed triangular prisms 1-Ln3 and tetrahedra 2-Ln4 (Ln = LaIII, SmIII, EuIII), have been constructed for the first time, through either one-pot subcomponent self-assembly or postassembly metalation. In contrast to the known tetrahedral cages based on transition metals, the pillar-typed polyhedra were favored from the same organic components in the presence of lanthanides. Besides this, facile transmetalations between the 1-Ln3 polyhedra endow cascade chameleonic luminescence. Meanwhile, the open metal sites and pendent amine groups on 1-Ln3 enable these polyhedra to catalyze the Henry reaction efficiently.

镧系元素共价有机多面体的自组装:骨架发光和高效催化。

首次构造了一系列多核镧系共价有机多面体(LnCOPs),包括柱型三角棱镜1-Ln 3和四面体2-Ln 4(Ln = La III,Sm III,Eu III),通过一锅子组件自组装或后组装金属化。与已知的基于过渡金属的四面体笼相反,在镧系元素的存在下,柱型多面体受到相同有机成分的青睐。除此之外,在1-Ln 3多面体之间容易进行的重金属化赋予级联Chaleleonic发光。同时,1-Ln上的开放金属位点和侧胺基团3使这些多面体有效地催化亨利反应。
