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

The prototype three-dimensional metal-organic framework Zn-2(BDC)(2)(Dabco)center dot 4DMF center dot 0.5H(2)O(MOF-1) and two-dimensional Zn-2(BDC)(2)(H2O)(2)center dot(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.
