He, Liang;Tong, Lifen;Liu, Xiaobo research published 《 Durable crosslinked films based on poly (arylene ether nitrile) materials for ultrahigh temperature applications over 300°》, the research content is summarized as follows. Searching for outstanding films with high temperature resistance has sparked fierce interests in the electronics industry. In this study, a novel high-temperature-resistance phthalonitrile end-capped polyarylene ether nitrile (HTR-PEN-Ph) film was fabricated via crosslinking reaction, applying two different curing programs as contrast. The fabricated HTR-PEN-Ph films were verified through FTIR, gel content test to be confirmed the crosslinking reaction. Then thermal results elucidated that PEN-Ph films treated with two-stage curing program possessed a superior glass transition temperature (T_g) in comparison with untreated one, increasing by 165-270°. Besides, an evident increment of 5 weight% decomposition temperature (T5%) was seen from the HTR-PEN-Ph film, which was 27-43° higher than the untreated one. Furthermore, the HTR-PEN-Ph films exhibited notable dielec. stability over 300° and mech. properties after the two-stage curing program. Based on these satisfactory results, this study is of great potential to be applied in the field of industrial manufacture to fabricate a range of high-performance films.

He, Xian;Qi, Jiayue;Chen, Menghao;Lv, Jiangbo;Xiao, Hang;Hu, Jianghuai;Zeng, Ke;Yang, Gang research published 《 Preparation of novel bio-based imine-containing phthalonitrile resin through the nucleophilic reaction in green solvent》, the research content is summarized as follows. Nucleophilic reactions, as extensive and easily implementable reactions in organic chem., play a significant role in the mol. design of organic compounds and polymer materials. In current sustainable development strategies, nucleophilic reactions are also being shifted towards green chem. In this paper, phthalonitrile (PN) resin, a thermoset prepared by nucleophilic substitution reaction, was selected for a case study to investigate the application and reusability of the ‘green solvent’ di-Me carbonate (DMC) in the nucleophilic substitution reaction. This research employed naturally existing vanillin and tyramine for the synthesis of a fully bio-based bisphenol bearing a Schiff base structure (VTBP). Then VTBP was converted to a novel bio-based PN (VTPN) through a nucleophilic substitution reaction in DMC, and the DMC was recovered and reused through a rotary evaporation The structure, curing behavior, and performance of the cured resin of the synthesized VTPN were characterized. The results suggest that the Schiff base may promote and participate in the crosslinking of nitrile, with a relatively high performance achieved under moderate curing conditions. This study provides a new green implementation scheme for high-performance polymers prepared through nucleophilic reactions, as well as for the high-performance and efficient utilization of widely existing bio-based aldehydes and amines.

Giddaerappa;Manjunatha, Nemakal;Shantharaja;Hojamberdiev, Mirabbos;Sannegowda, Lokesh Koodlur research published 《 Tetraphenolphthalein cobalt(II) phthalocyanine polymer modified with multiwalled carbon nanotubes as an efficient catalyst for the oxygen reduction reaction》, the research content is summarized as follows. Oxygen reduction reaction (ORR) is the main reaction at the cathode of a fuel cell that utilizes Pt/C as the benchmark catalyst. Due to sluggish activity, high cost, rare abundance, and durability issues, Pt/C must be replaced by nonprecious, stable, and easily synthesizable materials. This work involves the synthesis of novel, simple, low-cost, and environmentally friendly phenolphthalein-bearing cobalt(II) phthalocyanine polymer, poly(Co^IITPpPc) dyad, as an efficient catalyst for ORR. The results of anal. characterizations reveal the formation of the poly(Co^IITPpPc) polymer in the pure state. To further enhance the catalytic response of poly(Co^IITPpPc), a hybrid composite is prepared using poly(Co^IITPpPc) and multiwalled carbon nanotubes (MWCNTs) that increase the surface area and conductivity The poly(Co^IITPpPc) and hybrid composite are sep. deposited on the electrode surfaces. The electron microscopy images confirm the uniform distribution of the poly(Co^IITPpPc) mols. on the electrode surface and MWCNTs. The poly(Co^IITPpPc) and hybrid composite electrodes are evaluated for ORR, and the hybrid composite exhibits better onset potential at 0.803 V vs. reversible hydrogen reference electrode for ORR according to linear sweep voltammograms (LSVs). The obtained data are superior compared to those of other carbon-based redox-active materials reported previously and nearer to those of the benchmark catalyst (Pt/C). The rotating disc electrode measurement of the hybrid composite electrode confirms the total number of electrons involved in ORR to be four. Furthermore, the hybrid composite electrode exhibits an excellent stability for 100 LSV scans. The synergistic effect of poly(Co^IITPpPc) and MWCNTs leads to the surprisingly high ORR activity due to the improved surface area, conductivity, and interfacial confined surface.

Gonzalez, Andreia C. S.;Felgueiras, Alexandre P.;Aroso, Rafael T.;Carrilho, Rui M. B.;Pereira, Mariette M. research published 《 Al(III) phthalocyanine catalysts for CO₂ addition to epoxides: Fine-tunable selectivity for cyclic carbonates versus polycarbonates》, the research content is summarized as follows. A sustainable synthetic methodol. to prepare bifunctional cationic imidazolyl and neutral tert-butylphenoxy Al(III)-phthalocyanine complexes is described, using ultrasound irradiation to synthesize the phthalonitrile precursors, followed by microwave-assisted cyclotetramerization. The metallophthalocyanine catalysts were applied in the coupling reaction of CO₂ with epoxides, where the structure of the phthalocyanine was shown to determine the reaction selectivity towards the formation of cyclic carbonates vs. polycarbonates. The cationic imidazolyl phthalocyanines operate as efficient bifunctional catalysts to promote the CO₂ cycloaddition to terminal epoxides (styrene oxide, epichlorohydrin, propylene oxide and allyl glycidyl ether), leading to TONs up to 1414 and 100% selectivity for cyclic carbonates, without the need of using any co-catalyst. On the other hand, the neutral 4-tert-butylphenoxy Al(III) phthalocyanine catalyzed the copolymerization reaction between CO₂ and cyclohexene oxide, in the presence of PPNCl as co-catalyst, with TON = 814, providing the first example of a metallophthalocyanine catalyst with full selectivity for formation of polycarbonates.

Demirelli, Kadir;Abubakar, Abdullahi Musa;Tuncer, Hulya;Salih, Bekir research published 《 Preparation, characterization and electrical behaviors of greenish single-chain polymeric molecule-via intramolecular ball type cobalt phthalocyanines/ graphite oxide composites》, the research content is summarized as follows. The greenish single-chain polymeric mol.-ball type CoPc (SCPM-ball type CoPc) was prepared via the intramol. formation of cobalt phthalocyanine from polystyrene-co-poly[4,4′-((((4-vinylbenzyl)azanediyl)bis(ethane-2,1diyl))bis(oxy))diphthalonitrile] [P(PNDEAMSt12%-co-St)] (linear copolymer precursor) under diluted conditions at 150°C. The structure of SCPM-ball type CoPc was confirmed by FT-IR, MALDI-TOF-MS, UV and SEM. The conversion dependence of the exptl. activation energy was readily determined by an isoconversional method. So, the Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS) showed that the linear copolymer precursor’s activation energies were as average 128.7 kJ/mol and 124.0 kJ/mol and those of SCPM-ball type CoPc were average 161.9 kJ/mol and 153.8 kJ/mol, resp. Conductivity mechanism of composites was suggested as Correlated Barrier Hoping (CBH). The linear copolymer precursor/graphite oxide (GO) composite has a significant performance for dielec. constant of 696.4 at 130°C, but it was with a comparatively greater dielec. loss. Those of SCPM-ball type CoPc/14wt% GO increased virtually the same relative ratio.

Chen, Xinggang;Cai, Yanqing;Qu, Xiongwei;Chen, Jun;Zheng, De research published 《 Preparation of a self-catalyzed amino-epoxy phthalonitrile resin with a large processing window》, the research content is summarized as follows. To expand the processing window of phthalonitrile resins, a novel self-catalyzed amino-epoxy 4-aminophenoxy phthalonitrile-resorcinol diglycidyl ether phthalonitrile (APRE-PN) resin was prepared via a two-step method of reacting amino and epoxy groups at a low temperature and then reacting nitrile with nitrile groups at a high temperature The amine-epoxy, epoxy-nitrile, and nitrile-nitrile reactions were confirmed by Fourier-transform IR spectroscopy and differential scanning calorimetry, and the probable polymerization mechanism was elucidated. The significant decrease in the m.p. of the proposed APRE-PN prepolymers dramatically expands the processing window (173°C) for an entire class of phthalonitrile matrixes. The APRE-PN resin exhibits excellent thermal stability and dynamic mech. properties owing to the presence of triazine, phthalocyanine, and oxazoline structures. The improved preparation method provides a new path for the preparation of phthalonitrile resins with large processing windows and new opportunities for the use of this type of thermosetting matrix in manufacturing various composite materials and prepregs.

T.;Duong, Hai M.;Lee, Poh Seng;Zhao, Xiaoxu;Koh, Ming Joo;Yan, Ning;Loh, Kian Ping research published 《 Addressing the quantitative conversion bottleneck in single-atom catalysis》, the research content is summarized as follows. Single-atom catalysts (SACs) offer many advantages, such as atom economy and high chemoselectivity; however, their practical application in liquid-phase heterogeneous catalysis is hampered by the productivity bottleneck as well as catalyst leaching. Flow chem. is a well-established method to increase the conversion rate of catalytic processes, however, SAC-catalyzed flow chem. in packed-bed type flow reactor is disadvantaged by low turnover number and poor stability. In this study, we demonstrate the use of fuel cell-type flow stacks enabled exceptionally high quant. conversion in single atom-catalyzed reactions, as exemplified by the use of Pt SAC-on-MoS₂/graphite felt catalysts incorporated in flow cell. A turnover frequency of approx. 8000 h^-1 that corresponds to an aniline productivity of 5.8 g h^-1 is achieved with a bench-top flow module (nominal reservoir volume of 1 cm³), with a Pt₁-MoS₂ catalyst loading of 1.5 g (3.2 mg of Pt). X-ray absorption fine structure spectroscopy combined with d. functional theory calculations provide insights into stability and reactivity of single atom Pt supported in a pyramidal fashion on MoS₂. Our study highlights the quant. conversion bottleneck in SAC-mediated fine chems. production can be overcome using flow chem.
