Tetraphenylmethane, tetraphenylsilane, and simple derivatives with substituents that do not engage in hydrogen bonding typically crystallize as close-packed structures with essentially no space available for the inclusion of guests. In contrast, derivatives with hydrogen-bonding groups are known to favor the formation of open networks that include significant amounts of guests. To explore this phenomenon, we synthesized six new derivatives 5a–5e and 6a of tetraphenylmethane and tetraphenylsilane with urethane and urea groups at the para positions, crystallized the compounds, and determined their structures by X-ray crystallography. As expected, all six compounds crystallize to form porous three-dimensional hydrogen-bonded networks. In the case of tetraurea 5e, 66% of the volume of the crystals is accessible to guests, and guests can be exchanged in single crystals without loss of crystallinity. Of special note are: (i) the use of tetrakis(4-isocyanatophenyl)methane (1f) as a precursor for making enantiomerically pure tetraurethanes and tetraureas, including compounds 5b, 5c; and (ii) their subsequent crystallization to give porous chiral hydrogen-bonded networks. Such materials promise to include chiral guests enantioselectively and to be useful in the separation of racemates, asymmetric catalysis, and other applications.Key words: crystal engineering, molecular tectonics, hydrogen bonding, networks, porosity, urethanes, ureas, tetraphenylmethane, tetraphenylsilane.

Studies of how hydrogen bonding can be used to control molecular association continue to yield exciting discoveries in supramolecular chemistry. A simple way to make molecules that associate predictably is to link carefully selected cores to functional groups that form multiple hydrogen bonds according to reliable patterns. Bifunctional molecules constructed according to this strategy can associate to form linear aggregates robust enough to warrant the name supramolecular polymers, even though the bifunctional monomers are joined only by hydrogen bonds. More complex molecules with multiple hydrogen-bonding sites can be devised so that neighbors are held in predetermined positions, giving crystalline solids with predictable architectures and properties not previously seen in other materials. Initial studies of the ability of such compounds to associate in solution and in the molten state suggest that hydrogen-bonded networks can be purposefully designed to create novel par- tially ordered liquid materials, including liquid crystals, gels, and fluids with unusual rheological properties.
