Zhao, Dongmu;Ouyang, Ancheng;Wang, Xianglei;Zhang, Wei;Cheng, Guanghui;Lv, Bin;Liu, Wei research published 《 Synthesis, crystal structure and biological evaluation of thyroid cancer targeting photosensitizer for photodynamic therapy》, the research content is summarized as follows. With the increasing of thyroid cancer worldwide, there urgently demands new mild theranostic strategies for treatment of recurrence of thyroid cancer to overcome the side-effects of the clin. practices (¹³¹I). In this work, photodynamic therapy (PDT) was first explored for treatment of thyroid cancer by incorporating iodomethane choline onto the phthalocyanine through either axial or peripheral substitution. Due to the extraordinary nonaggregation properties in aqueous solution, the axial choline substituted SiPc 1 shows much higher singlet oxygen generation and fluorescence emission than ZnPc 2 and 3 with peripheral substituted cholines. Their photodynamic activities in different type of thyroid cancer cells were clearly compared, disclosing that SiPc 1 is the most promising candidate for PDT of thyroid cancer.

Zhi, Qianjun;Jiang, Rong;Liu, Wenping;Sun, Tingting;Wang, Kang;Jiang, Jianzhuang research published 《 Atomic CoN₃S₁ sites for boosting oxygen reduction reaction via an atomic exchange strategy》, the research content is summarized as follows. It is vitally important to develop high-efficiency low-cost catalysts to boost oxygen reduction reaction (ORR) for renewable energy conversion. Herein, an A-CoN₃S₁@C electrocatalyst with at. CoN₃S₁ active sites loaded on N, S-codoped porous carbon was produced by an at. exchange strategy. The constructed A-CoN₃S₁@C electrocatalyst exhibits an unexpected half-wave potential (0.901 V vs. reversible hydrogen electrode) with excellent durability for ORR under alk. conditions (0.1 M KOH), superior to the com. platinum carbon (20 weight% Pt/C). The outstanding performance of A-CoN₃S₁@C in ORR is due to the pos. effect of S atoms doping on optimizing the electron structure of the at. CoN₃S₁ active sites. Moreover, the rechargeable zinc-air battery in which both A-CoN₃S₁@C and IrO₂ were simultaneously served as cathode catalysts (A-CoN₃S₁@C &IrO₂) exhibits higher energy efficiency, larger power d., as well as better stability, compared to the compound Pt/C&IrO₂-based zinc-air battery. The present result should be helpful for developing lower cost and higher performance ORR catalysts which is expected to be used in practical applications in energy devices.

Zhu, Lei;Liang, Gaolei;Guo, Chuanpan;Xu, Miaoran;Wang, Minghua;Wang, Changbao;Zhang, Zhihong;Du, Miao research published 《 A new strategy for the development of efficient impedimetric tobramycin aptasensors with metallo-covalent organic frameworks (MCOFs)》, the research content is summarized as follows. Two bimetallic CoNi-based metallo-covalent organic frameworks (MCOFs) were prepared and explored as the sensitive platforms of impedimetric aptasensors for efficient detection of tobramycin (TOB). The two CoNi-MCOFs were constructed using metallophthalocyanine tetra-amine (MPc-TA, M = Co²⁺ or Ni²⁺) and 4,4′-(1,10-phen-anthroline-2,9-diyl) dibenzaldehyde (PTD) as building units and further coordinating to the secondary metal ions (Ni²⁺ or Co²⁺) by phenanthroline. Interestingly, the immobilization ability of CoPc-TA-PTD(Ni) to TOB-targeted aptamer is higher than that of NiPc-TA-PTD(Co) due to its stronger binding interactions to aptamer. As a result, the CoPc-TA-PTD(Ni)-based aptasensor shows the superior TOB detection ability, giving a low detection limit of 0.07 fg mL^-1 and satisfied sensing performances, such as high selectivity, good reproducibility, and excellent stability. Also, the aptasensor shows the acceptable applicability for detecting TOB in milk or chicken egg. This MCOFs-based sensing strategy could be extensively applied to detect other analytes by anchoring the corresponding probes.

Zuo, Linsen;Wu, Chenjiang;Tong, Lifen;Liu, Xiaobo research published 《 Improving interfacial properties of polyarylene ether nitrile/aramid fiber composite through hydrogen bonding interaction combined with molecular weight adjustment》, the research content is summarized as follows. Aramid fiber (AF)-reinforced composite is a material with high performance and great potential. In this work, polyarylene ether nitrile terminated with phthalonitrile (PEN-t-Ph) is used to modify the AF surface, and hydrogen bonds are formed between the AF and PEN-t-Ph resin, as shown by Fourier IR anal. Then modified AF (m-AF)/PEN-t-Ph composite laminate is prepared by hot-pressing, and the influence of mol. weight of PEN-t-Ph on performance of the m-AF/PEN-t-Ph composite laminate is studied. The PEN-t-Ph were named PEN-1, PEN-2, PEN-3 and PEN-4 according to mol. weight from large to small. And the mech. properties and interface compatibility of m-AF/PEN-n composite laminates initially increase and then decrease as the mol. weight of the PEN-t-Ph resin decreases. The m-AF/PEN-3 composite laminate has the best mech. performance with an interlaminar shear strength of 94 MPa that is 95% higher than the lowest values among the four samples. In addition, m-AF/PEN-3 has the best impact strength of 133.70 kJ/m², and in the dynamic mech. anal. test, m-AF/PEN-3 has a leading storage modulus with 62 GPa at 120°C which is 50 GPa higher than for the lowest sample. In general, the mol. weight of the PEN-t-Ph resin has a greater impact on performance of the m-AF/PEN-t-Ph composite laminates, and appropriate adjustment of mol. weight of the PEN-t-Ph resin will help improve the comprehensive performance of the m-AF/PEN-t-Ph composite laminate and provides a new way for preparing AF-reinforced materials.

The photophysicochem. features of the newly synthesized phthalocyanines includiing fluorescence, photodegradation, and singlet oxygen quantum yields were studied in different solvents such as DMF, DMSO, and THF to explore their potential as suitable photosesitizers. Solvent effect on the photophys. and photochem. parameters of the tetra-substituted phthalocyanines bearing the 4-{[(1E)-(4-fluorophenyl)methylene]amino}phenoxy, 4-{[(1E)-(4-chlorophenyl)methylene]amino}phenoxy, 4-{[(1E)-(4-bromophenyl)methylene]amino}phen-oxy groups were investigated, as well. In comparison to the known Schiff base containing phthalocyanines, the newly synthesized compounds exhibited higher singlet oxygen values. Singlet oxygen yields of the complexes (7–9) were obtained between 0.57 and 0.86. Due to the high singlet oxygen yields of compounds (7–9), they can be listed as photosensitizers in the implementation of photocatalytic applications such as photodynamic therapy (PDT) which is an efficient method for the treatment of cancer.

Zhang, Heng;Li, Minghui;Wang, Caiyun;Huang, Gang;Liu, Meina;Sun, Jing;Fang, Qiang research published 《 A highly heat-resistant phthalocyanine resin based on a bio-based anethole》, the research content is summarized as follows. A phthalonitrile-containing monomer derived from a plant oil (anethole) has been successfully synthesized by a facile two-step reaction in an overall yield of 84%. Upon high temperature, this monomer is converted to a cured phthalocyanine resin in the presence of a catalyst, 4,4′-bis(3-aminophenoxy)diphenyl sulfone (m-BAPS). Such a cured resin displays good thermostability including high glass transition temperature (T_g > 450°C), low thermal expansion coefficient (CTE, near 62.99 ppm °C^-1 from 25 to 400°C) and high char yield (>72% at 1000°C). These data are comparable to those of the most of the common phthalocyanine resins derived from the fossil resource, suggesting that the phthalonitrile-containing monomer is a suitable precursor for the preparation of the ablation-resistant materials used on the surface of the spacecrafts.

Recently, Li-CO₂ battery has gradually become a research hotspot due to its high discharge capacity, energy d. and environmental benefits. However, it has been an important problem for researchers because of its slow decomposition kinetics and difficult to generalize to practical application. Herein, we prepared copper polyphthalocyanine-carbon nanotubes composites (CuPPc-CNTs) by solvothermal in-situ polymerization of copper phthalocyanine on the surface of carbon nanotubes as cathode for reversible Li-CO₂ batteries, which exhibits a high discharge capacity of 18,652.7 mAh·g^-1 at c.d. of 100 mA·g^-1, 1.64 V polarization at 1,000 mA·g^-1, and a stable cycles number of 160 is close to 1,630 h of charge-discharge process at 200 mA·g^-1. Copper polyphthalocyanine has highly efficient copper single-atom catalytic sites with excellent CO₂ adsorption and activation, while carbon nanotubes provide a conductive network. The synergistic effect of the two compounds enables it to have excellent catalytic activity. The d. functional theory (DFT) calculation proved that the addition of copper polyphthalocyanine significantly improved the CO₂ adsorption and activation process. This study provides an opportunity for the research of covalent organic polymers (COPs) single-atom catalyst in Li-CO₂ battery field.

The pursuit of a desirable photocatalytic technol. has always been accompanied by photocatalyst design and development, marking high activity, long-term stability, and low cost. Herein, an in-situ deposition approach is used to integrate plasmonic 0D Ag nanoparticles on the surface of 2D slice-like 2,9,16,23-tetranitrocopper(II) phthalocyanine (CuPc) sensitized 1D Bi₂MoO₆ nanofibers (Ag-CuPc/Bi₂MoO₆) for visible-light-induced tetracycline (TC) photocatalysis. Benefiting from the combination of 2D CuPc sensitization, and surface plasmon resonance (SPR) effect of 0D Ag nanoparticles, we exptl. find that the Ag-CuPc/Bi₂MoO₆ nanofibers boost the visible-light utilization efficiency, promote charge transfer, and separation, and accelerate electron redox transformation in TC photocatalysis. The superior photocatalytic activity is attributed to the strong interfacial interaction, and Z-scheme heterojunction synergy in Ag-CuPc/Bi₂MoO₆ nanofibers. This work opens new horizons for the delicate design of promising Z-scheme visible-light photocatalysts for the removal of antibiotics in wastewater, realizing water purifications.
