Wang, Chongchong;Li, Yanqing;Yang, Weijie;Zhou, Lin;Wei, Shaohua research published 《 Nanozyme with Robust Catalase Activity by Multiple Mechanisms and Its Application for Hypoxic Tumor Treatment》, the research content is summarized as follows. Utilizing catalase-mimicking nanozymes to produce O₂ is an effective method to overcome tumor hypoxia. However, it is challenging to fabricate nanozymes with ultrahigh catalytic activity. Palladium nanosheet (Pd NS), a photothermal agent for photothermal therapy (PTT), has superior catalase-mimicking activity. Here, titanium dioxide (TiO₂) is used to modify Pd NS (denoted Pd@TiO₂) by a simple one-step method to improve its catalytic activity about 8 times. The enhancement mechanism′s fundamental insights are discussed through experiments and d. functional theory calculations Next, zinc phthalocyanine is loaded on Pd@TiO₂ to form a nanomotor (denoted PTZCs) with the synergistic activities of photodynamic therapy and PTT. PTZCs inherit the catalase activity of Pd@TiO₂ to facilitate the decomposition of endogenous H₂O₂ to O₂, which can relieve tumor hypoxia and propel PTZC migration to expand the reach of PTZCs, further enhancing its synergistic treatment outcome both in vitro and in vivo. It is proposed that this work can provide a simple and effective strategy for catalytic activity enhancement and bring a critical new perspective to studying and guiding the nanozyme design.

Srivishnu, K. S.;Naresh, Madarapu;Laxmikanth Rao, J.;Giribabu, Lingamallu research published 《 Photo-induced intramolecular electron transfer in phenoxazine-phthalocyanine donor-acceptor systems》, the research content is summarized as follows. Donor-Acceptor (D-A) systems based on phenoxazine – phthalocyanine (PXZ-Pc) and phenoxazine – zinc phthalocyanine (PXZ-ZnPc) have been designed and synthesized. Both D-A systems are characterized using various spectroscopic and electrochem. techniques including in-situ methods. Optical absorption studies suggest that both Soret and Q bands of these D-A systems are hypsochromically and bathochromically shifted, when compared to its individual constituents. The study supported by theor. calculations shows clearly that there exists a negligible electronic communication in the ground state between donor phenoxazine and acceptor phthalocyanine. However, attractively, both D-A systems exhibit noteworthy fluorescence emission quenching (90-99%) of the phthalocyanine emission compared to its reference compounds The fluorescence emission quenching featured at the excited-state intramol. photoinduced electron transfer from ground state of phenoxazine to the excited state of phthalocyaine/zinc phthalocyanine. The rates of electron-transfer (kET) of these D-A systems are found in the range of 5.7 x 108 to 2.8 x 109 s^-1 and are according to solvent polarity.

Singh, Ajit Shankar;Shukla, S. K.;Mishra, Preeti;Pandey, A. K. research published 《 Synthesis and thermal evaluation of novel mono- and bis-adamantylated resorcinol-based phthalonitrile resins with enhanced solubility》, the research content is summarized as follows. Phthalonitrile (PN) resins are high-temperature-resistant thermosetting polymers which find applications in military as well as aerospace owing to their outstanding performance. At present, most of the PN resins are melt-processed and cured at high temperature via resin transfer molding owing to their poor solubility in common organic solvents. In the present, embodiment efforts have been made to change the PN resin backbone with adamantane as potential functionality. Mono- and novel bis-adamantylated resorcinols 1a and 1b have been synthesized via Amberlyst-15 solid acid resin-catalyzed Friedel-Crafts alkylation reaction, as precursor material for the synthesis of novel phthalonitrile (PN) resin monomers 2a and 2b, resp. The study includes structural and thermal characterization of resin monomers 2a and 2b along with their solubility in common organic solvents. These resins when cured to their thermosets have demonstrated thermal stability ~723 K (5% mass loss) with no glass transition temperature (Tg) up to 673 K. The resin monomers show very good solubility in industry-friendly organic solvents like acetone, Et acetate, Me Et ketone and Me iso-Bu ketone.

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.

V. research published 《 Low-melting phthalonitrile monomers containing maleimide group: Synthesis, dual-curing behavior, thermal and mechanical properties》, the research content is summarized as follows. Novel dual-functional phthalonitrile monomers containing a maleimide group were synthesized and characterized. Ortho, meta, and para isomers were obtained and only the meta-isomer can be considered as a low melting phthalonitrile monomer with a m.p. of 107.4°C. Anal. of the dual-curing behavior of monomers showed radical homopolymerization of maleimides followed by phthalonitrile polymerization with the formation of isoindoline, triazine, and phthalocyanine ring structures. Two alternative copolymerization processes of maleimide groups via ene reaction and ring-opening amidation were investigated. The approach of dual-curing maleimide and phthalonitrile fragments in a single mol. allowed combining the excellent inherent mech. properties of bismaleimide resins and the outstanding thermo-oxidative stability of phthalonitriles. After curing of both functional groups impact strength was as high as 11.81 kJ m^-2, flexural strength was 108 MPa, Young’s modulus was 4.38 GPa. On the contrary, T_g of this polymeric system was above 370°C and T_5% was higher than 450°C in air.

The novel Zn(II) tetra-β-[4-(2-styryl-benzimidazole-1-yl)] phthalocyanine (ZnTSBPc) and elucidated the structure using various spectroscopic and electrochem. techniques. ZnTSBPc pigment is anchored to magnetite ore particle (Fe₃O₄) and this composite is immobilized on glassy C electrode (GCE) and used for the electrochem. sensing of thiocyanate (SCN^–) using cyclic voltammetry (CV). The GCE/ZnTSBPc and GCE/ZnTSBPc- Fe₃O₄ displayed linear response in the dynamic quant. range 0.150 to 3.400 μM and 0.090 to 8.640 μM with sensitivity values 383.918 and 618.670 μA μM^-1 cm^-2, resp. Also, GCE/ZnTSBPc and GCE/ZnTSBPc-Fe₃O₄ electrodes were employed for designing a chronoamperometric sensor for thiocyanate in the quant. range 0.050-0.450 μM, with sensitivity values 166.350 and 3852.687 μA μM^-1 cm^-2, resp. Results inferred that ZnTSBPc-Fe₃O₄ composite exhibited higher catalytic performance compared to ZnTSBPc administered GCE. The enhanced activity is ascribed to the increase in conductivity with an enhanced surface area of the composite. Also, the fabricated sensor exhibited good stability and superior selectivity for the thiocyanate in presence of coexisting mols. The developed ZnTSBPc-Fe₃O₄ sensor was assessed for the determination of SCN^– in biol. (saliva and urine) samples which delivered satisfactory results.

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.

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.
