An Azine-Linked Covalent Organic Framework
Journal of the American Chemical Society, 2013Condensation of hydrazine with 1,3,6,8-tetrakis(4-formylphenyl)pyrene under solvothermal conditions yields highly crystalline two-dimensional covalent organic frameworks. The pyrene units occupy the vertices and the diazabutadiene (-C═N-N═C-) linkers locate the edges of rohmbic-shaped polygon sheets, which further stack in an AA-stacking mode to ...

Porous, Crystalline, Covalent Organic Frameworks
Science, 2005Covalent organic frameworks (COFs) have been designed and successfully synthesized by condensation reactions of phenyl diboronic acid {C 6 H 4 [B(OH) 2 ] 2 } and hexahydroxytriphenylene [C 18 H 6 ...

Covalent organic frameworks (COFs) are a new and emerging class of porous and crystalline materials that are formed via the connection of organic subunits through covalent bonds. Their great structural flexibility allows for the realisation of COFs based on a modular principle, where the respective building blocks can be hand-picked and designed ...

Covalent organic frameworks in tribology - A perspective
Advances in Colloid and Interface ScienceTwo-dimensional covalent organic frameworks (2D COFs) are an emerging class of crystalline porous materials formed through covalent bonds between organic building blocks. COFs uniquely combine a large surface area, an excellent stability, numerous abundant active sites, and tunable functionalities, thus making them highly attractive for numerous ...

Homochiral Helicene Covalent Organic Frameworks
Journal of the American Chemical SocietyWhile chirality is common in nature, creating synthetic macromolecules with controlled chirality remains a significant challenge. Here we report the synthesis of homochiral frameworks by exploring M and P enantiomers of [7]Helicene as building units to create chiral skeletons.
