Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons. 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Nitriles are found in many useful compounds. One of the most common occurrences of nitriles is in Nitrile rubber. Name: 4-Nitrophthalonitrile.
Wang, Jihua;Dong, Wenyue;Si, Zhenjun;Cui, Xu;Duan, Qian research published 《 Synthesis and enhanced nonlinear optical performance of phthalocyanine indium polymers with electron-donating group porphyrin by efficient energy transfer》, the research content is summarized as follows. In this study, a phthalocyanine indium (InPcOH) and three porphyrin derivatives (Por2a, Por2b, Por2c) were successfully synthesized. Three kinds of novel four-arm star-shaped poly(propylene oxide) (PPO) with core of InPcOH and chain-end of porphyrin derivatives, named InPc-(PPOx-Por2n)4 (n = a-c), were achieved through the InPcOH as initiator by ring-opening polymerization From fluorescence spectra, InPc-(PPOx-Por2n)4 polymers revealed weaker emission intensity at 704 nm in comparison with InPc-(PPO29)4, proving energy transfer (ET) pathway from Por2a-2c to InPc, which could be established by theor. study. Due to ET pathway, InPc-(PPOx-Por2n)4 polymers showed stronger nonlinear optical (NLO) performance than InPc-(PPO29)4 polymer. Among InPc-(PPOx-Por2n)4, InPc-(PPO33-Por2b)4 obtained the most outstanding NLO performance exhibiting imaginary third-order susceptibility (Im[χ(3)]) of 6.25 x 10-11 esu, which could ascribe the efficient ET pathway from Por2b to InPc based on the appropriate spatial structure and small energy gap of Por2b. Moreover, the InPc-(PPO33-Por2b)4/polymethyl methacrylate (PMMA) composites were prepared for applying actually, and it displayed a prominent Im[χ(3)] value of 22.4 x 10-11 esu and an outstanding limiting threshold of 0.14 J/cm2. The remarkably enhanced NLO performance exhibited by InPc-(PPO33-Por2b)4/PMMA composites in comparison with that in Me methacrylate solution prove a feeblish aggregation effect in PMMA matrix, which indicate the great potential of our polymers for real application in NLO field. This research could furnish a novel designing approach in terms of NLO materials that exhibit great performance.
Name: 4-Nitrophthalonitrile, 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.
