An intrinsically porous trianglimine macrocycle 1 is reported to display energy-efficient and cost-effective adsorptive properties by selectively separating -1,2-dichloroethene (-DCE) from an equimolar - and -DCE mixture with a purity of over 96%. The selectivity is enhanced by host/guest C-H⋯π intermolecular interactions. Moreover, the macrocycle can be reused many times without any decrease in performance, which further supports the sustainability of using molecular sieves in chemical separation.
据报道，一种具有内在多孔性的三角咪咯大环 1 能够通过从等摩尔的 - 和 -DCE 混合物中选择性地分离出 -1,2-二氯乙烯（-DCE），从而显示出节能且具有成本效益的吸附性能，其纯度超过 96%。这种选择性是通过主体/客体 C-H···π 分子间相互作用增强的。此外，该大环可以多次重复使用而不会降低性能，这进一步支持了在化学分离中使用分子筛的可持续性。
