A Chromium Terephthalate-Based Solid with Unusually Large Pore Volumes and Surface Area

Résumé

We combined targeted chemistry and computational design to create a crystal structure for porous chromium terephthalate, MIL-101, with very large pore sizes and surface area. Its zeotype cubic structure has a giant cell volume (È702,000 cubic angstroms), a hierarchy of extra-large pore sizes (È30 to 34 angstroms), and a Langmuir surface area for N 2 of È5900 T 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.
