Further development of metal–organic frameworks (MOFs) requires an establishment of hierarchical interaction within the framework. Herein, we report a series of mesoporous rare‐earth (RE) MOFs that are constructed from an unusual 12‐connected π‐stacked pyrene secondary building unit (SBU) and a typical 12‐connected RE 6 cluster (RE=Eu, Y, Yb, Tb, Ce). The judicious design of a butterfly‐shape pyrene ligand with a tert ‐butyl substituent enables the formation of the disordered 12‐connected organic SBUs on its strong intermolecular π–π interactions. The assembly of 12‐connected inorganic cuboctahedron SBUs and 12‐connected organic distorted hexagonal prism SBUs generates an unprecedented network that can be further simplified into a 4,4‐connected pts net linked from planar square and tetrahedra. This work provides fresh insights into the design and synthesis of frameworks constructed from coordinatively, covalently, and noncovalently linked building units.
