Ning, Yi;Li, Dian-sen;Wang, Ming-cun;Jiang, Lei research published 《 Bio-resourced eugenol derived phthalonitrile resin for high temperature composite》, the research content is summarized as follows. Eugenol (EG) is an abundant renewable compound that has been widely used in the synthesis of bio-based thermosetting resin, but there are few reports on the phthalonitrile (PN) resin derived from EG. In this study, a new kind of bio-based PN resin (MEG-PN) derived from EG derivative was successfully synthesized. PN is a traditional class of high-performance thermosets with poor processability for its ultra-high m.p. and curing temperature The MEG-PN resin possesses excellent processability: its melting temperature is much lower (77°C), and it can be cured at a moderate temperature (281°C) in the absence of curing agents. The cured MEG-PN resin exhibited great heat resistance according to its 5% weight loss temperature at 448°C and its char yield percentage as high as 75.6% at 800°C under nitrogen. The properties of the carbon-fiber reinforced MEG-PN composite were comparable to those of petroleum-based PN resins: the glass transition temperature was around 397°C; the flexural strength and modulus were as high as 756 MPa and 119 GPa, resp. Overall, a bio-based PN thermoset with great comprehensive performance was synthesized possessing the potential in the application of advanced composite.

Nie, Wo;Yang, Jian;Wu, Jiahui;Hu, Liu research published 《 Synthesis and photophysical properties of vice-like 1,8-naphthalimide fluorescent sensor for sensitive detection of Mn2+ and Zn2+》, the research content is summarized as follows. Building fluorescence sensors with intelligent performance on detecting target substrate in our living environment is of great significance. Two 1,8-naphthalimide fluorescence sensors with “vice” like phthalic acid recognition groups (NAC1, NAC2) were designed and synthesized via a facile method. The photophys. properties of the two compounds were investigated and compared. The research on structure-performance difference showed that NAC2, containing a n-dodecylamino group at the 4-position of the 1,8-naphthalimide moiety, had better fluorescence “turn-off” performance to Mn2+ and Zn2+. DFT calculations were applied to verify the results. NAC2 can detect the two kinds of metal ions within 1 min, and the detection limit was resp. determined to be 0.040 mg/L (for Mn2+), 0.085 mg/L (for Zn2+). NAC2 was also applied in the practical sample anal., indicating that it is a potential visualization tool in environmental monitoring.

Nguyen, Yennie H.;Soares, Joao Vitor;Nguyen, Sami H.;Wu, Yanyu;Wu, Judy I.;Teets, Thomas S. research published 《 Platinum(II)-Substituted Phenylacetylide Complexes Supported by Acyclic Diaminocarbene Ligands》, the research content is summarized as follows. The authors introduce phosphorescent Pt aryl acetylide complexes supported by tert-butyl-isocyanide and strongly σ-donating acyclic diaminocarbene (ADC) ligands. The precursor complexes cis-[Pt(CNtBu)2(CCAr)2] (4a–4f) are treated with diethylamine, which undergoes nucleophilic addition with one of the isocyanides to form the cis-[Pt(CNtBu)(ADC)(CCAr)2] complexes (5a–5f). The new compounds incorporate either electron-donating groups (4-OMe and 4-NMe2) or electron-withdrawing groups [3,5-(OMe)2, 3,5-(CF3)2, 4-CN, and 4-NO2] on the aryl acetylide. Exptl. HOMO-LUMO gaps, estimated from cyclic voltammetry, span the range of 2.68-3.61 eV and are in most cases smaller than the unsubstituted parent complex, as corroborated by DFT. In the ADC complexes, peak photoluminescence wavelengths span the range of 428 nm (2a, unsubstituted phenylacetylide) to 525 nm (5f, 4-NO2-substituted), with the substituents inducing a red shift in all cases. The phosphorescence E0,0 values and electrochem. HOMO-LUMO gaps are loosely correlated, showing that both can be reduced by either electron-donating or electron-withdrawing substituents on the aryl acetylides. The photoluminescence quantum yields in the ADC complexes are 0.044-0.31 and the lifetimes are 4.8-14μs, a factor of 1.8-10x higher (for ΦPL) and 1.2-3.6x longer (for τ) than the resp. isocyanide precursor (ΦPL = 0.014-0.12, τ = 2.8-8.2μs).

In recent years, the concentrations of carbon dioxide (CO2) in the environment have been rising at a disturbing rate, and accordingly, there is a global goal to reduce the Earth’s atm. CO2 to achieve a balanced climate. An efficient heterogeneous CO2 fixation catalytic system was designed purposefully based on the conjugation of multiwall carbon nanotube (MWCNT) with tetra-amino cobalt phthalocyanine (Co-PcTA) through an efficient Ugi four-component reaction (Ugi-4CR). The successful manufacture of catalyst was authenticated by various methods such as SEM, EDS, ICP, TGA XRD, and FT-IR. Subsequently, the catalytic performance of the cobalt phthalocyanine-conjugated MWCNT (Co-PcTA/MWCNTs) was investigated in the preparation of cyclic carbonates via the CO2 fixation reaction. The optimal reaction conditions are 25 mg of generated catalyst, 13 mg tetrabutylammonium bromide (TBAB) as a co-catalyst, 2.5 bar CO2 pressure, at 80°C, and 1 h. The remarkable benefits of the present catalyst are efficiency, high CO2 absorption capacity, rapid reaction, mild reaction conditions, non-hazardous, reusability, operational simplicity, high yields, and no cobalt leaching in the reaction media.

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.

Nazeri, Mohammad Taghi;Javanbakht, Siamak;Nabi, Mohadese;Shaabani, Ahmad research published 《 Copper phthalocyanine-conjugated pectin via the Ugi four-component reaction: An efficient catalyst for CO2 fixation》, the research content is summarized as follows. Pectin was used as a green support in this study to construct an efficient heterogeneous catalytic system based on the conjugation of metal phthalocyanines. To end this, pectin was first oxidized with periodate oxidant agent to effectively immobilize a tetra-amino copper phthalocyanine (Cu-PcTA) through a green, simple, and an efficient one-pot Ugi four-component reaction (Ugi-4CR). Then, the catalytic activity of the copper phthalocyanine-conjugated pectin was investigated in the CO2 fixation reaction to cyclic carbonates. Optimum catalytic conditions were as follows: 30 mg of prepared catalyst, 3 bar CO2 pressure, 90°C, 2 h, and TBAB as a co-catalyst. Pectin could successfully improve the catalytical properties of the Cu-PcTA over the CO2 fixation reaction.
