Diamonds are forever: A diamond-like framework in which the C–C bonds are replaced with rigid phenyl rings (see picture) is not only structurally stable but also has a large internal surface area. This porous aromatic framework (PAF-1) demonstrates high uptake capacities of hydrogen and carbon dioxide as well as benzene and toluene vapors, and has an unprecedented surface area of 7100 m2 g−1.
