Tesselation of new porphyrin‐based network motifs was demonstrated in crystals by incorporation of the diaminotriazine functions in the molecular building blocks. The title compound was synthesized and successfully applied in the construction of a uniquely structured solid which consists of flat multiporphyrin networks with very large voids, 2.2 × 2.2 nm 2 . These assemblies mutually interpenetrate each other, yielding a spectacular concatenated arrangement sustained in three dimensions by cooperative hydrogen bonding. The resulting multiporphyrin architecture resembles a molecular‐sieve material, having 0.6 nm wide channels which propagate through the crystal and are accessible to other molecules.
