Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. Formula: C8H3N3O2.
Wang, Jihua;Dong, Wenyue;Chen, Qiyue;Si, Zhenjun;Cui, Xu;Liu, Dajun;Duan, Qian research published 《 Syntheses and nonlinear optical behavior of four-arm star-shaped phthalocyanine indium polymers containing azobenzene》, the research content is summarized as follows. In this report, a series of novel four-arm star-shaped polymethyl methacrylate with core of phthalocyanine indium polymers (InPc-(PMMAx)4) were achieved with different mol. weights through Activator ReGenerated by Electron Transfer Atom Transfer Radical Polymerization, using the synthesized phthalocyanine indium (InPc-Br) as initiator. The InPc-(PMMAx)4 polymers were characterized by NMR, FT-IR, GPC, UV-Vis and PL spectroscopy. The nonlinear optical (NLO) properties of InPc-(PMMAx)4 polymers were investigated by the Z-scan technique and it revealed that InPc-(PMMA16)4 obtained satisfactory NLO properties with imaginary third order susceptibility (Im[χ(3)]) of 16.4 x 10-12 esu. Furthermore, reacting polymer InPc-(PMMA16)4 with NaN3 and 1-(4-nitrophenyl)-2-(4-(prop-2-yn-1-yloxy) phenyl) diazene (Azo-yne) through click reaction, a novel InPc polymer InPc-(PMMA16-b-Azo)4 was successfully synthesized. InPc-(PMMA16-b-Azo)4 displayed a weak fluorescence at 707 nm compared to InPc-(PMMA16)4, demonstrating the energy transfer (ET) process between Azo and InPc, which could be proved by d. functional theory. Because of the ET process, InPc-(PMMA16-b-Azo)4 exhibited a better NLO performance than InPc-(PMMA16)4, with Im[χ(3)] of 20.7 x 10-12 esu. In addition, the InPc-(PMMA16-b-Azo)4/PMMA complexes were prepared for the convenience of practical application, and it exhibited an excellent Im[χ(3)] value of 30.2 x 10-12 esu and a satisfactory limiting threshold of 0.04 J/cm2. The significantly enhanced NLO properties of InPc-(PMMA16-b-Azo)4/PMMA complexes demonstrate a weaker aggregation effect in polymethyl methacrylate matrix than in Me methacrylate solution Our study provides a promising design strategy to synthesize high performance NLO materials for practical applications.
Formula: C8H3N3O2, 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.
