Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 1835-49-0, formula is C8F4N2, Name is Tetrafluoroterephthalonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves. Name: Tetrafluoroterephthalonitrile.
Ling, Honglei;Jin, Jianyong research published 《 Improved synthesis route and performance of azide modified polymers of intrinsic microporosity after thermal self-crosslinking》, the research content is summarized as follows. A new azide modified biscatechol monomer was first obtained and characterized by single-crystal XRD, but its polymerization only afforded a low mol. weight azide-containing polymer of intrinsic microporosity (PIM-N3). The high-mol. PIM-N3 was then obtained via post-modification on PIM-Me, prepared by the fluoride-mediated PIM synthesis method developed by our group in 2015. The crosslinking temperature was set at 220°C based on the thermogravimetric anal. (TGA) data. The thermal self-crosslinking of PIM-N3 significantly enhanced gas permeability. The 6-h crosslinked PIM-N3 (PIM-N3-6 h) exhibited the best combination of CO2 permeability, and selectivity for CO2 over N2 and CH4, traversing the 2008 Robeson upper bound.
Name: Tetrafluoroterephthalonitrile, Tetrafluoroterephthalonitrile can react with alkyl grignard reagents to form 4-alkyltetraflurorobenzonitriles. It acts as a four electron donor ligand. Tetrafluoroterephthalonitrile can be used to synthesize polymers of intrinsic microporosity. It has been used to study UV rearranged polymers of teh PIM-1 type membrane for the efficient separation of H2 and CO2.
Tetrafluoroterephthalonitrile reacts with alkyl Grignard reagents to form corresponding 4-alkyltetrafluorobenzonitriles. Tetrafluoroterephthalonitrile acts as a four-electron donor ligand and forms tungsten(II)η 2-nitrile complexes.
Tetrafluoroterephthalonitrile is a hydroxyl group-containing organic chemical compound . It has been used in analytical chemistry as a reagent for the determination of peptide binding constants and disulfide bonds. Tetrafluoroterephthalonitrile binds to nucleophilic sites on proteins, such as the pim-1 protein, and can be used to transport other molecules across cell membranes. In addition, it has been used to produce polymers for use in analytical chemistry. This chemical is also able to bind with magnetic particles under constant pressure conditions, which makes it useful for optical sensor applications. , 1835-49-0.
