以灵活的羧基配体5,5′-[（1,4-苯基双（亚甲基））双（氧）]二对苯二甲酸（H4L）为配体，构建了具有稀有恰巴石（CHA）拓扑结构的三维铜金属-有机骨架FJI-Y11。FJI-Y11具有较高的水稳定性，pH值范围为2至12，温度高达373 K。重要的是，FJI-Y11在77 K大气压下的动态柱突破实验中也表现出了较高的氢同位素分离效率。由于其优异的结构稳定性，FJI-Y11具有良好的再生性能，经过三次突破实验后仍保持较高的分离效率。
A three-dimensional copper metal—organic framework with the rare chabazite (CHA) topology namely FJI-Y11 has been constructed with flexibly carboxylic ligand 5,5′-[(1,4-phenylenebis(methylene))bis(oxy)]diisophthalic acid (H4L). FJI-Y11 exhibits high water stability with the pH range from 2 to 12 at temperature as high as 373 K. Importantly, FJI-Y11 also shows high efficiency of hydrogen isotope separation using dynamic column breakthrough experiments under atmospheric pressure at 77 K. Attributed to its excellent structural stability, FJI-Y11 possesses good regenerated performance and maintains high separation efficiency after three cycles of breakthrough experiments.
