Covalent Organic Frameworks (COFs) Biphenyl Ligand

An acetonitrile functionalised bridging ligand linker for COFs in application of visible light-induced hydrogen production and photocatalyst and biosensors

Specifications | MSDS | Literature and Reviews

4,4'-Biphenyldiacetonitrile, CAS number 7255-83-6, has a linear biphenyl linker with acetonitrile groups on both ends. 4,4'-Biphenyldiacetonitrile is commonly used in the preparation of microporous organic networks with aldehydes via the Knoevenagel condensation.

Prepared by the Knoevenagel condensation of tri(4-formylphenyl)amine with 4,4'-biphenyldiacetonitrile, visible light harvesting microporous COF showed visible light absorption in 400 – 530 nm and vivid emission at 542 nm. The COF/TiO2–Pt composite exhibited promising activity and enhanced stability as a photocatalytic system for visible light-induced hydrogen production from water.

Olefin-linked chiral CCOF 18 with 2D layered tetragonal structure was obtained by Knoevenagel polycondensation of chiral tetrabenzaldehyde of dibinaphthyl-22-crown-6 with 4,4′-biphenyldiacetonitrile. Reduction of the olefin linkage of CCOF-18 produced C–C single bond linked framework CCOF-18-R, while retaining high crystallinity and porosity as well as high chemical stability in both strong acids and bases.
