TLDR
Covalent organic frameworks (COFs) have been designed and successfully synthesized by condensation reactions of phenyl diboronic acid and hexahydroxytriphenylene to form rigid porous architectures with pore sizes ranging from 7 to 27 angstroms.Abstract:
Covalent organic frameworks (COFs) have been designed and successfully synthesized by condensation reactions of phenyl diboronic acid {C6H4[B(OH)2]2} and hexahydroxytriphenylene [C18H6(OH)6]. Powder x-ray diffraction studies of the highly crystalline products (C3H2BO)6.(C9H12)1 (COF-1) and C9H4BO2 (COF-5) revealed expanded porous graphitic layers that are either staggered (COF-1, P6(3)/mmc) or eclipsed (COF-5, P6/mmm). Their crystal structures are entirely held by strong bonds between B, C, and O atoms to form rigid porous architectures with pore sizes ranging from 7 to 27 angstroms. COF-1 and COF-5 exhibit high thermal stability (to temperatures up to 500 degrees to 600 degrees C), permanent porosity, and high surface areas (711 and 1590 square meters per gram, respectively).read more

Covalent organic frameworks as metal-free heterogeneous photocatalysts for organic transformations
TL;DR: In this article, a 2D-COF with permanent porosity and high surface area and large pore volume was proposed for photocatalytic organic transformations. But the porosity was not exploited to obtain a high crystallinity and high stability.

Computer simulation of the adsorption of light gases in covalent organic frameworks.
TL;DR: Grand canonical Monte Carlo simulations of argon, hydrogen, and methane adsorption in four covalent organic frameworks give a strong indication that at least one material in this class, COF-102, could meet or exceed the Department of Energy's target of 180 cm3 (STP)/cm3 for P = 35 bar and room temperature.

An ordered mesoporous organosilica hybrid material with a crystal-like wall structure.
TL;DR: The surfactant-mediated synthesis of an ordered benzene–silica hybrid material has an hexagonal array of mesopores and crystal-like pore walls that exhibit structural periodicity, and it is expected that other organosilicas and organo-metal oxides can be produced in a similar fashion, to yield a range of hierarchically ordered mesoporous solids with molecular-scale pore surface periodicity.
