The deliberate construction of isoreticular eea ‐metal–organic frameworks (MOFs) ( Cu‐eea‐1 , Cu‐eea‐2 and Cu‐eea‐3 ) and rtl ‐MOFs ( Co‐rtl‐1 and Co‐rtl‐2 ) has been accomplished based on the ligand‐to‐axial pillaring of supermolecular building layers. The use of different metal ions resulted in two types of supermolecular building layers (SBLs): Kagome ( kgm ) and square lattices ( sql ) which further interconnect to form anticipated 3D‐MOFs. The isoreticular expansion of (3,6)‐connected Cu‐MOFs has been achieved with desired eea ‐topology based on kgm building layers. In addition, two (3,6)‐connected Co‐ rtl ‐MOFs were also successfully constructed based on sql building layers. The Cu‐ eea ‐MOFs were shown to act as hydrogen storage materials with appreciable amount of hydrogen uptake abilities. Moreover Cu‐ eea ‐MOFs have also exhibited remarkable CO 2 capture ability at ambient condition compared to nitrogen and methane, due to the presence of amide functionalities.
