Recently, porous organic cage crystals have become a real alternative to extended framework materials with high sp. surface areas in the desolvated state. Although major progress in this area has been made, the resulting porous compounds are restricted to the microporous regime, owing to the relatively small mol. sizes of the cages, or the collapse of larger structures upon desolvation. Herein, we present the synthesis of a shape-persistent cage compound by the reversible formation of 24 boronic ester units of 12 triptycene tetraol mols. and 8 triboronic acid mols. The cage compound bears a cavity of a min. inner diameter of 2.6 nm and a maximum inner diameter of 3.1 nm, as determined by single-crystal X-ray anal. The porous mol. crystals could be activated for gas sorption by removing enclathrated solvent mols., resulting in a mesoporous material with a very high sp. surface area of 3758 m2 g-1 and a pore diameter of 2.3 nm, as measured by nitrogen gas sorption.
