Abstract
Maximizing Molecular Pore Diameters: Amorphous materials, such as activated carbon, can have pore diameters of several nanometers, but the synthesis of ordered structures with very large pore diameters is often thwarted by the creation of interpenetrating networks or difficulties in removing guest molecules. Deng et al. (p. 1018 ) avoided these problems in the synthesis of metal-organic frameworks (MOFs) with very large diameters (some exceeding 3 nanometers) by using a combination of short and very long linking groups. The compounds formed channels almost 10 nanometers in diameter that could be visualized by electron microscopy and that were large enough to accommodate protein molecules.Keywords
