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. Application of C8F4N2.
Chen, Xiudong;Zhang, Hang;Yan, Ping;Liu, Bo;Cao, Xiaohua;Zhan, Changchao;Wang, Yawei;Liu, Jin-Hang research published 《 Bipolar fluorinated covalent triazine framework cathode with high lithium storage and long cycling capability》, the research content is summarized as follows. Organic materials with adjustable structures and wide sources are expected to become potential candidates for com. cathodes of lithium-ion batteries (LIBs). However, most organic materials have unstable structures, poor conductivity, and are easily soluble in electrolytes, resulting in unsatisfactory lithium storage performance. Covalent-organic frameworks have attracted extensive attention due to their stable frame structures, adjustable pore structures and functionalized official groups. Herein, a fluorinated covalent triazine framework (FCTF) is synthesized by a simple ion-thermal method. Compared with the fluorine-free covalent triazine frameworks (CTFs), the introduction of fluorine improves the lithium storage performance of CTF. When used as a cathode for lithium ion batteries, FCTF can retain a reversible capacity of 125.6 mA h g-1 after 200 cycles at a c.d. of 100 mA g-1. Besides, it also delivers 106.3 mA h g-1 after 400 cycles at a c.d. of 200 mA g-1 with 0.03% decrease per cycle (from 40 to 400 cycles).
Application of C8F4N2, 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 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.
