Molecular Tectonics: Porous Cleavable Networks Constructed by Dipole‐Directed Stacking of Hydrogen‐Bonded Sheets

Carefully selected combinations of directional forces can be used to rationally engineer crystals with particular anisotropic features. This approach has led to the generation of cleavable molecular crystals with parallel 15-Å channels by dipole-directed stacking of hydrogen-bonded sheets (see crystal structure). The network remains undeformed when guests included in the channels are exchanged.
