Popis:	Employing a rational design strategy to construct porous metal–organic frameworks (MOFs) with predictable structures for specific applications still remains one of the most compelling challenges. Here, a novel two-dimensional (2D) bilayer (FJI-H16) based on Zn/Cd heterometal clusters has been constructed throughout a heterometal strategy, further introducing pillar ligands with different sizes and flexibilities that expand such 2D bilayer structures into two novel three-dimensional (3D) frameworks (FJI-H17, FJI-H18), in which both the pore size and flexibility of the new-formed 3D frameworks can be tuned. Further gas adsorption research indicates that the less porous FJI-H16 has the highest H2 adsorption, while the very porous FJI-H17 has the highest CO2 adsorption. The relationship between gas adsorption properties and pore characteristics also has been investigated, which will provide a potential strategy that can improve gas adsorption in designing porous MOFs.
