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). 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. 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. Reference of 31643-49-9.
Mei, Lan;Cui, Xu;Wei, Juncheng;Duan, Qian;Li, Yanhui research published 《 Metal phthalocyanine-based conjugated microporous polymer/carbon nanotube composites as flexible electrodes for supercapacitors》, the research content is summarized as follows. Conjugated microporous polymers with active functional groups have attracted more and more attentions in energy conversion systems. However, their low elec. conductivity results in low capacitance, thus limiting their practical application. Herein, conjugated microporous polymer with triphenylamine aldehyde linked to metal phthalocyanines (MNC) is synthesized and then compounded with high-conductivity carbon nanotubes (CNTs) (denoted as CoNCCs) by vacuum filtration. Moreover, CoNCCs exhibit flexibility, which could be served as a self-standing and binder-free flexible electrode of supercapacitors. As a result, the optimized CoNCCs as the flexible electrode show high specific capacitance of 213.4 F g-1 at 0.5 A g-1. In addition, the higher capacity retention rate 85.3% can be retained after 1750 cycles at 20 A g-1. The good electrochem. properties can be attributed to the synergistic effect and strong dual-phase interaction between MNC and CNTs. This work opens the way to develop high-performance and low environmental footprint organic electrode materials for SCs.
Reference of 31643-49-9, 4-Nitrophthalonitrile, also known as 4-Nitrophthalonitrile, is a useful research compound. Its molecular formula is C8H3N3O2 and its molecular weight is 173.13 g/mol. The purity is usually > 95%.
4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., 31643-49-9.
