Here, we report a covalent and supramolecular hybrid organic framework with interlocked poly[n]rotaxane residues, which enables the fabrication of layered thin sheets. The dumbbell of the pseudo-polyrotaxane was connected covalently via an efficient cooperative CB-AAC reaction, and connected supramolecularly in the second dimension upon self-assembly by the dint of donor-acceptor or π-π interactions. The secondary structure of this material has been characterized by NMR spectroscopy, SEM, TEM, high-resolution TEM and AFM technologies. This unique structure (covalent and supramolecular hybrid connection, interlocked poly[n]rotaxane residues) opens up the way for designing novel frameworks with emergent properties.
