Metal–organic frameworks (MOFs) provoke intensive research interests on separations of small gas molecules. By introducing a coordinative phosphate group into a carboxylic acid linker, a ligand 4,4′-(hydroxyphosphoryl) dibenzoic acid (H₃hpda) was successfully synthesized and used to construct microporous phosphonocarboxylate framework [Cu₃(hpda)₂·DMF·2H₂O]·3DMF·H₂O (DMF = N,N-dimethylformamide) and [Mg₃(μ₂-OH₂)₂(OH₂)₂(hpda)₂]·3DMF·2H₂O. Both of them possess narrow approachable channels and exhibit excellent performance on selective separation of light hydrocarbons (C₁–C₂), presenting a promising ligand design strategy for the construction of porous material aiming for natural gas upgrading.

用于轻烃分离的膦酰基羧酸盐金属-有机骨架的合理设计†

金属有机框架（MOF）引起了对小气体分子分离的深入研究兴趣。通过将配位磷酸基团引入羧酸连接基，成功合成了配体4,4'-（羟基磷酰基）二苯甲酸（H ₃ hpda），并用于构建微孔膦酰基羧酸酯骨架[Cu ₃（hpda）₂ ·DMF·2H ₂ O]·3DMF·H ₂ O（DMF = ñ，ñ二甲基甲酰胺）和[镁₃（μ ₂ -OH ₂）₂（OH ₂）₂（HPDA）₂ ]·3DMF·2H ₂O.它们都具有狭窄的可接近通道，并且在选择性分离轻质烃（C ₁ -C ₂）方面表现出优异的性能，为用于天然气升级的多孔材料的构造提出了有希望的配体设计策略。
