A novel autocatalytic phthalonitrile monomer [4,4′-(((((oxy-bis [4,1-phenylene]) bis (azanediyl)) bis (methylene)) bis (2-methoxy-4,1-phenylene)) bis (oxy)) diphthalonitrile, OPD] is obtained by nucleophilic substitution of 4-nitro-phthalonitrile and bisphenol compound [4,4′-(((oxy bis [4,1-phenylene]) bis (azanylylidene)) bis (methanylylidene)) bis (2-methoxyphenol)]. Bisphenol compound is a reductant with secondary amine groups of Schiff base derived from the reaction of vanillin and 4,4′-diaminodiphenylether. The OPD monomer has a self-catalytic polymerizing reaction. OPD monomer has good processability, and the processing window was 130°C. Moreover, OPD polymer [poly(OPD)] shows higher glass-transition temperature (345°C). The 5% and 10% thermal decomposition temperatures of poly(OPD) and char yield at 800°C are 407, 451°C, and 69%, resp. To further improve the properties of poly(OPD), the OPD monomer was modified by multi-functional fluorene-based benzoxazine monomers (MFFB) due to their excellent reaction activities. The results showed that OPD/MFFB systems had high reaction activities. The similar thermal stabilities between OPD and MFFB can give stable and excellent thermal stability to the poly(OPD/MFFB). Compared with poly(OPD), the Tg values of poly(OPD/MFFB) were significantly increased, and their stiffness values were reduced. The tensile, flexural, and impact properties for poly(OPD/MFFB) were improved significantly.

Wang, Taisheng;Shen, Lei;Wang, Haoxiang;Zhang, Na research published 《 A highly selective fluorescent sensor for ratiometric detection of cyanide in aqueous solution and solid states》, the research content is summarized as follows. Designing fluorescent sensors for selective detection of CN^– in aqueous and even solid states are still rarely reported due to the aggregation-caused quenching (ACQ) effect. In this paper, we report a novel fluorescent probe C-1. Due to the AIE effect, C-1 displayed obvious orange-red fluorescence with emission peak centered at 597nm in aqueous solution and solid state. Under the influence of electron withdrawing cyano and ester groups, the vinyl C=C bond was easy to be attacked by nucleophilic CN^–, which destroyed the conjugated bridge and also blocked the ICT process between the donor and the acceptor. The emission band shifted from 597 nm to 475 nm consequently. Other anions have no effect on the fluorescence of C-1. Thus, C-1 could be used as a selective CN^– sensor. The UV-visible and fluorescent measurement confirmed the interactions between C-1 and CN^–. ¹H NMR titration method further demonstrated the detection mechanism. The sensitivity and detection limit of C-1 were measured to be 5.97 x 10⁴ M^-1 and 1.2 μM resp. Due to the solid-state emission nature, C-1 immersed test strip was prepared and used as an effective test kit to detect CN ion.

Wang, Shuai;Deng, Li-Hong;Du, Yi-Fei;Song, Xian-Liang research published 《 Graphene carbon black as catalyst support: The influences of iron phthalocyanine loading and carbon black additive amount on the power generation performance of direct glucose fuel cell》, the research content is summarized as follows. Fast accessibility of oxygen reduction reaction (ORR) species to a catalyst surface with the efficient utilization of every catalytic site plays a critical role in catalysis. Therefore, engineering of the structure and morphol. of catalyst supports to both anchor and expose catalytic sites at three-phase-boundaries, accelerating the mass transport of reaction-species through the active sites, can be regarded as one of the most prospective methods to promote the efficient utilization of every catalytic site, giving prominent cell performance. Herein, two series of oxygen reduction reaction catalysts are prepared: reduced graphene oxides (rGO) with different loading amounts of iron phthalocyanine TFePc/rGO-X (X = 1,2,3,4 and 5); and TFePc/rGO-3 that is intercalated by different amounts of carbon black TFePc/rGO/CB-Y (Y = 1,2,3,4 and 5). The catalytic activities and stabilities of these catalysts were evaluated by cyclic voltammetry and linear sweep voltammetry. As expected, the 3D rGO/CB/rGO network is demonstrated as a singular catalyst-loading platform, with interlayer spacing that could be elaborately tuned via a simple carbon black intercalation. This enables ORR-species to be efficiently transported to each catalytic site. Besides, the optimal catalyst of TFePc/rGO/CB-3 exhibits more pos. ORR peak potential than Pt/C catalyst. More significantly, in a practical cell, the cell performances were highly consistent with ORR active and the first-best cell performance of 0.86 mWcm-2 in power d. was achieved for TFePc/rGO/CB-3. This is mainly attributed to the synergistic effect of rGO and carbon black, as well as the π-π interaction between rGO and TFePc.

Wang, Minghua;Zhu, Lei;Zhang, Shuai;Lou, Yafei;Zhao, Shuangrun;Tan, Quan;He, Linghao;Du, Miao research published 《 A copper(II) phthalocyanine-based metallo-covalent organic framework decorated with silver nanoparticle for sensitively detecting nitric oxide released from cancer cells》, the research content is summarized as follows. A novel metallo-copper phthalocyanine-based covalent-organic framework (CuTAPc-MCOF) doped with silver nanoparticles (denoted as CuTAPc-MCOF@AgNPs) was developed. CuTAPc-MCOF was synthesized using Cu(II) 4′,4′′,4′′′,4′′′′-tetra-amine phthalocyanine (CuTAPc) and 2,9-bis[p-(formyl)phenyl]-1,10-phenanthroline as building blocks through the Schiff base condensation reaction. The basic characterizations revealed that CuTAPc-MCOF demonstrated extended π-system and possessed the phenanthroline group, which can be coordinated with Ag. Consequently, it endowed the CuTAPc-MCOF@AgNPs nanohybrid with good biol. compatibility, boosted electron transfer, and produced abundant catalytic active sites. As such, the CuTAPc-MCOF@AgNPs nanohybrid illustrated superior biocompatibility and excellent electrocatalytic activity, thereby showing remarkable electrocatalytic performance for electro-oxidizing nitric oxide (NO) released from living cancer cells. The sensing properties of the CuTAPc-MCOF@AgNPs-based sensor were measured by cyclic voltammetry and amperometry techniques. The CuTAPc-MCOF@AgNPs-based electrochem. sensor showed a high sensitivity of 29.1 ΜA ΜM^-1 cm^-2 and a low detection limit of 12.6 nM within the concentration range of 0.18 ΜM to 17.1 ΜM toward NO, together with excellent selectivity, high reproducibility and repeatability, and good stability. Overall, our sensing strategy showed potential application in detecting NO released from living cancer cells and diagnosing biol. processes.

Wang, Liang;Guo, Xiang;Zhang, Feng;Li, Nanwen research published 《 Blending and in situ thermally crosslinking of dual rigid polymers for anti-plasticized gas separation membranes》, the research content is summarized as follows. The polybenzimidazoles (PBI) has been employed as blends and macromol. crosslinkers into bromomethylated polymers of intrinsic microporosity (PIM-Br) to prepare anti-plasticized gas separation membrane. Interestingly, the PBI showed excellent miscibility with PIM-Br probably due to the interaction between the benzimidazole and -CN groups, and thus a series of flexible, tough and transparent membranes were obtained by simply blending. After thermal treatment of the blending membrane, the crosslinked PIM-Br/PBI membranes with ionic and covalent crosslinking were achieved as confirmed by XPS results. Although the blending PIM-Br/PBI membranes showed the decreased gas permeabilities due to the lower gas permeability of PBI moieties, the increased gas permeabilities of PIM-Br/PBI membrane has been observed after crosslinking without significant sacrificing of selectivity. Moreover, higher crosslinking temperature induced the higher gas permeability. The PIM-Br/PBI membrane having PBI content of 5 wt% treated at 300°C has a CO₂ permeability of 3313.7 Barrer which is much higher than that of the PIM-Br/PBI blending membrane (1645.3 Barrer) probably due to the formation of more open matrix in membrane after crosslinking. However, comparable CO₂/CH₄ selectivity of ∼13 were observed for all of the crosslinked membranes. Importantly, both of the blending and thermal crosslinking between PIM-Br and PBI resulted in the excellent CO₂ anti-plasticization ability of the membrane. Particularly, a single gas plasticization pressure as high as more than 600 psi and mixed-gas plasticization resistance for crosslinked PIM-Br/PBI have been observed This value is much higher than that of the pristine PIM-Br membrane (100 psi).

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.
