Summary: A sensing material with 2,4-dinitrophenyl hydrazine attachment was synthesized and characterized. The chemosensor exhibited selective colorimetric sensing for F- ions, which was thoroughly investigated using UV-Vis, NMR, and DFT analysis. The limit of detection and association constant were found to be 1.37 μM and 3.09 x 107 M-1, respectively. The chemosensor underwent color change from yellow to pink due to hydrogen bonding induced deprotonation caused by the high electronegativity of F-. The paper strip kit of the chemosensor was successfully applied for sensing F- ions.

Summary: A series of acyclic aminooxycarbene (AAOC)-ligated ruthenium metathesis catalysts were developed and exhibited outstanding catalytic efficiencies and selectivities in the ethenolysis of methyl oleate and cis-cyclooctene. The ambiphilic character of AAOC ligands, combining strong sigma-donors and pi-acceptors, contributed to the enhancement of catalytic activity and selectivity of the ruthenium catalysts. This research represents a rare example of acyclic carbene-ruthenium catalysts demonstrating high catalytic efficiency and excellent selectivity in olefin metathesis reactions.

Summary: In this study, atomically dispersed CuN3 catalysts supported by two different types of zirconia were fabricated to investigate the influence of the support on the electrocatalytic CO2 reduction towards CO. The CuN3/NC/T-ZrO2 catalyst exhibited excellent performance at a wide range of potentials, attributed to the acidic uncoordinated Zr4+ sites of T-ZrO2 and the conductivity enhancement of N-doped carbon (NC). Density functional theory calculations confirmed the effective decrease of Gibbs free energy for CO2 to CO conversion by T-ZrO2. Additionally, this study provided a promising strategy for tuning catalytic activity and selectivity by controlling the phase of the support, offering insights into the electrocatalytic CO2RR process.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
