Abstract Use of preformed metal‐organic polyhedra (MOPs) as supermolecular building blocks (SBBs) for the synthesis frameworks (MOFs) remains underexplored due to lack robust functionalized MOPs. Herein we report use polycarboxylate cuboctahedral Rh II ‐MOPs constructing highly‐connected MOFs. Cuboctahedral MOPs were with carboxylic acid groups on their 12 vertices or 24 edges through coordinative covalent post‐synthetic routes, respectively. We then used each isolated ‐MOP 12‐c 24‐c rhombicuboctahedral SBBs that, upon linkage metallic secondary units (SBUs), afford bimetallic The assembly a pre‐synthesized SBB 4‐c paddle‐wheel SBU, and 3‐c triangular Cu SBU gave rise MOFs having ftw (4,12)‐c rht (3,24)‐c topologies,
