Abstract
We combined targeted chemistry and computational design to create a crystal structure for porous chromium terephthalate, MIL-101, withverylargeporesizes and surface area. Its zeotype cubic structure has a giant cell volume (∼702,000 cubic angstroms), a hierarchy of extra-large pore sizes (∼30 to 34 angstroms), and a Langmuir surface area for N 2 of ∼5900 ± 300 square meters per gram. Beside the usual properties of porous compounds, this solid has potential as a nanomold for monodisperse nanomaterials, as illustrated here by the incorporation of Keggin polyanions within the cages.

- Initial hydrogen storage measurements were ∼0.45 and 3.75 weight percent at 293 K and 77 K respectively at 2 MPa. The values at 77 K seem to be the highest for MOFs after the contestation of previous results ( 3 ).
- Initial introduction of semiconducting ZnS nanoparticles in the pores of MIL-101 was successfully achieved with a ZnS/Cr ratio close to 0.5.
- Incorporation of ibuprofen within MIL-101 has been achieved in large amounts (∼1 g of drug per gram of MIL-101) with a total release of the drug within a few days.
