Crystallized frameworks with giant pores: Are there limits to the possible?

Article Abstract:

The combination of mastered chemistry and of computer simulations pushes forward the limits of the classical approach and allows the full determination from powder diffraction data of architectures with cells of several hundred thousand cubic angstroms with hierarchies of giant pores and unprecedented Langmuir surfaces in the domain of porous solids with inorganic or hybrid frameworks. The different limits induced by this new approach are analyzed.

Prospects for Giant Pores

Article Abstract:

Crystalline porous materials are usually made out of aluminosilicate zeolites, but researchers are discovering new families of porous materials. The hope is that these new materials can be used for new applications, such as sensors and nanotechnology. The iron phosphate mineral cocoxenite, for instance, has pores that are 14 angstrom in diameter.

Microporous porphyrin solids

Article Abstract:

Metalloporphyrins are exceedingly useful building blocks for the design and synthesis of molecularly based solids. Porous solids that are thermally robust and retain their internal porosity upon loss of solvates are created by using several polyfunctionalized porphyrins.
