为了阐明结构对稳定性和气体吸附性能的影响，构建了三种多孔Zn（II）金属有机框架，NKU-106，NKU-107和NKU-108。由酰胺官能化的四羧酸配体组装的NKU-106和NKU-107表现出低稳定性，从而表现出差的气体吸附能力。然而，当四羧酸配体的一个取代基被吡唑基团取代时，所得NKU-108显示出改善的热稳定性和化学稳定性以及对CO2和C2烃的良好吸附能力。这一结果表明，配位基团优化是提高金属有机骨架（MOFs）稳定性和气体吸附性能的有效策略，从而为今后设计和合成具有实际应用价值的多孔MOFs提供了非常有价值的信息。
In order to elucidate the effect of the structure on stability and gas adsorption performance, three porous Zn(II) metal–organic frameworks, NKU-106, NKU-107, and NKU-108, have been constructed. NKU-106and NKU-107assembled from acylamide functionalized tetracarboxylate ligand exhibit low stability and thereby poor gas adsorption ability. However, when one isophthalate moiety of the tetracarboxylate ligand is replaced with a pyrazole group, and the resulting NKU-108shows improved thermal and chemical stability as well as good adsorption capacities with respect to CO2and C2hydrocarbons. This result demonstrates that coordination group optimization is an effective strategy to improve the stability and gas adsorption properties of metal–organic frameworks (MOFs) and thus provides very valuable information for future design and synthesis of porous MOFs for practical application.
