      Voltammetric reduction of a series of 1,4-dimethoxypillar[m]arene[n]quinones (DMP[m]A[n]Qs) has been studied on glassy carbon electrode in acetonitrile. All the quinone units showed relative electron uptake behavior except 1,4-dimethoxypillar[5]quinones (DMP[5]Qs). The electrochemical behavior of the systems being investigated was obviously different when compared with linear analogues of quinones systems. This is attributed to the close proximity of redox-active sites as well as the delocalization of electrons on the aromatic rings.

Simultaneously doping appropriate amounts of Fe and B into the ternary doped N, S, P-rGO composite produced a synergistic effect for enhancing ORR activity, which endowed the prepared catalyst with even higher ORR performance than that of the commercial Pt/C catalyst in alkaline electrolytes.

      Porous CoF2 spheres are synthesized using a safe and inexpensive ammonium fluoride as the fluorine sources by a facile one-pot solvothermal method. The nature of the synthesis can avoid using corrosive fluorine sources (such as HF), and additional high-temperature thermal treatment. The electrochemical performance reveals that the porous CoF2 spheres can retain approximately 127.4 mA·h·g−1 after 30 cycles with a high Coulombic efficiency of 97%.

      Juan Du, Kang Kang, Jinchuan Hu, Lijun Mao, Lihua Yuan and Wen Feng

      Version of Record online: 12 JUL 2016 | DOI: 10.1002/cjoc.201600237

      Thumbnail image of graphical abstract

      The interplay of molecular rigidity enforced by interior or exterior hydrogen bonding and affinity for binding halide anions is described to demonstrate the effect of intramolecular hydrogen bonding in anion recognition process. To this end pyridine-2,6-dicarboxamides 1 and 2, and aromatic oligoamides 3 and 4 containing intramolecular hydrogen bonds were explored for their ability in associating with tetrabutylammonium halide (Cl, Br, and I). The trimeric amide 3, which adopts a crescent conformation as revealed by single-crystal X-ray diffraction analysis, strongly binds chloride anion with binding constant as high as 379 L·mol−1 in chloroform. This is more than 6 times greater than the binding constant for the control receptor 2 with a backbone that is only partially rigidified.

    8. A Novel CdS/g-C3N4 Composite Photocatalyst: Preparation, Characterization and Photocatalytic Performance with Different Reaction Solvents under Visible Light Irradiation

      Version of Record online: 12 JUL 2016 | DOI: 10.1002/cjoc.201600251

      CdS/graphtic carbon nitride (CdS/g-C3N4) hybrid materials were synthesized by thermal polymerization and hydrothermal methods using Cd(CH3COO)2·2H2O, thioacetamide, and melamine as precursors. Upon visible light irradiation, a coupled system toward the selective oxidation of benzyl alcohol to benzaldehyde and the reduction of nitrobenzene into aniline was realized by the as-synthesized photocatalyst. Results indicate that CdS/g-C3N4 sample exhibits an outstanding photocatalytic performance for selective oxidation of benzyl alcohol and reduction of nitrobenzene. Further study suggests that the selective oxidation of benzyl alcohol to benzaldehyde is induced by the photoexcited holes and the reduction of nitrobenzene into aniline is triggered by the photoexcited electrons. Additionally, the catalyst can be recycled several times without noticeable deactivation.

    10. A Novel Ratiometric Oxygen Sensor Based On a Sextuple Hydrogen-Bonding Self-Assembly Molecular Heterodimer

      Version of Record online: 12 JUL 2016 | DOI: 10.1002/cjoc.201600257

      Thumbnail image of graphical abstract

      A novel hydrogen-bonding (HB) self-assembly heterodimer was synthesized. The inefficient energy transfer between the phosphor and fluorophore owing to the isolation by the rigid bulk hydrogen-bonding spacing moiety is advantageous to the simultaneous acquirement of ?uorescence/phosphorescence dual emission in neat-film state. Using this HB self-assembly heterodimer, neat-film-based ratiometric oxygen sensors showing strictly linear Stern-Volmer behavior in the full oxygen concentration range from 0 to 100 vol%, good photostability, good reversibility and rapid response/recovery times were demonstrated.

      HMG-CoA reductase inhibitors were widely used as lipid-lowing agents through effectively blocking the rate-limiting step of cholesterol biosynthesis. 8 analogs of Rosuvastatin were firstly prepared with different distance and functional group between the O5-hydroxyl group and terminal COOH group in the hydrophilic side-chain. In primary and secondary screening of the inhibitory activities against human HMG-CoA reductase, gem-difluoromethylenated derivatives exhibited more than 50% inhibition rate. Then 4 compounds with gem-difluoro group were further synthesized and evaluated in vitro, three compounds among them exhibited low single digital nmol/L IC50 values against HMG-CoA reductase. Molecular docking also well explained the observed special contribution of the gem-difluoro group.

      MnO2/Polyaniline/graphene composite as a supercapacitor electrode material was synthesized through an interfacial polymerization approach in the interface of oil/water phase. The as-synthesized MPG is characterized by Infrared spectroscopy, XRD, XPS, SEM and TEM, and its electrochemical performance is measured by cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy. The 3D nanostructure of MPG and loose nanorod structure of polyaniline (PANI) coated with round MnO2 pellets could be clearly observed. The maximum energy density of MPG is 45.4 Wh/kg (at a power density of 67.8 kW/kg) and the highest power density is 229.2 kW/kg (at an energy density of 25.7 Wh/kg). The capacitance retentions after 500 cycles at the scan rate of 5 mV/s for MGP composite and PANI/graphene are of 70.4% and 59.1%, respectively, and the capacitance values after 500 cycles are 158.4 F/g and 114.8 F/g, respectively. The improved performance of MPG is due to the 3D nanostructure, loose nanorod structure of PANI and stable support of graphene, which prevent the mechanical deformation effectively during the fast charge/discharge process and facilitate the diffusion of the electrolyte ions into the inner region of active materials. The composite material is very promising for the next generation of high-performance supercapacitors electrode.
