Abstract Interpenetrated metal–organic frameworks (MOFs) are often observed to show lower porosity than their non‐interpenetrating analogues. It would be highly desirable if the interpenetrated MOFs could still provide high stability, high rigidity, and optimal pore size for applications. In this work, an asymmetrical tricarboxylate organic linker was rationally designed for the construction of a copper(II)‐based microporous MOF with a twofold interpenetrated structure of Pt 3 O 4 topology. In spite of having structural interpenetration, the activated MOF shows high porosity with a Brunauer–Emmett–Teller surface area of 2297 m 2 g −1 , and high CO 2 (15.7 wt % at 273 K and 1 bar) and H 2 uptake (1.64 wt % at 77 K and 1 bar).
