Reversible Two-Dimensional−Three Dimensional Framework Transformation within a Prototype Metal−Organic Framework

The prototype three-dimensional metal−organic framework Zn2(BDC)2(Dabco)·4DMF·0.5H2O (MOF-1) and two-dimensional Zn2(BDC)2(H2O)2·(DMF) (MOF-2) can be reversibly transformed with each other in which the activated MOF-2 exhibits high selective gas adsorption with respect to C2H2/CO2 at room temperature.原型三维金属有机框架（metal−organic framework）Zn₂(BDC)₂(Dabco)·4DMF·0.5H₂O（MOF-1）与二维Zn₂(BDC)₂(H₂O)₂·(DMF)（MOF-2）可发生可逆的结构相互转化，其中活化后的MOF-2在室温条件下对乙炔（C₂H₂）/二氧化碳（CO₂）展现出优异的选择性气体吸附性能。
