Significance

The preparation of highly porous, crystalline organic frameworks by polycondensation reactions of p-phenyleneboronic acid is described. Extensive characterization studies, complemented by computation, suggest that the resulting 2-D sheets stack in staggered (graphite-like) or eclipsed (like in boron nitride) arrangements, depending upon the building blocks used. These thermally stable materials display pore sizes of 7-27 Å, and surface areas comparable to those of porous zeolites.
