Summary: Thiacalix[4]arene monosulfoxide 4 shows unique chemistry, with unprecedented derivatives in calixarene chemistry. It cannot be prepared by dealkylation, but forms a borate complex with a boron bound by neighboring phenolic oxygens and a sulfoxide group. Oxidation with Chloramine-T results in a complex oxathiane-based spiroheterocyclic part. X-ray analyses confirm the structures and propose feasible formation mechanisms, providing evidence of the distinction between thiacalixarene chemistry and classical CH2 analogues.

Summary: Accurate manipulation of ligands in clusters is challenging but important for controlling the properties and catalytic activity. In this study, two Cu(ii)-thiacalix[4]arene metallamacrocycles with different topologies were designed and synthesized, and the ligand substitution was successfully achieved. The effect of ligand tailoring on the electronic structure of clusters was revealed using theoretical calculations. The clusters showed promising catalytic activity for selective sulfide oxidation.

Summary: This study reports the single-crystal structure of the largest known mixed-valence silver nanoclusters protected by thiacalix[4]arenes and cyclohexanethiol. The structure consists of a metallic core with four concentric shells, surrounded by an organic skin. This work not only reveals the influence of macrocyclic ligands on the formation of large silver nanoclusters, but also provides a new structural archetype.

Summary: In this paper, a novel thiacalix [4]arene probe (s2) with a colorimetric and fluorogenic chemosensor for efficient detection of Ag+ ions was synthesized. The probe exhibited highly sensitive ratiometric recognition to Ag+ ions and showed a wide dynamic concentration range with a detection limit of 7.6 x 10-9 M. The recognition mechanism between the probe and Ag+ ions was confirmed by various characterization techniques.

Summary: In this study, the binding properties of Calix[4]arene 1, which has two lower-rim isoxazolylchloroanthracene groups, towards metal ions were investigated. It was found that compound 1 displayed high selectivity for Cu2+ ions and could detect their presence through changes in color and fluorescence. The reaction between Cu2+ and compound 1 involved the reduction of Cu2+ and the oxidation of the phenol group in compound 1. Experimental results and various spectroscopic techniques provided evidence for this redox reaction.

Summary: Two new Ni8Mo8 bimetallic coordination clusters, Ni8PMo8 and Ni8Mo8, were synthesized and characterized. These two clusters can be directly loaded on carbon paper and used as working electrodes for glucose detection and oxidation, showing distinguishable performances. This work provides a better understanding of the structure-property relationships in using substituted polyoxometalates for electrochemical applications and is helpful for building functional materials based on calixarenes or polyoxometalates.

Summary: A C-2-symmetry dianthrimide based probe and its hydroxide complex have been reported as a chromo-fluorogenic sensor for detecting trace amounts of water in polar aprotic solvents. The probe exhibits higher sensitivity towards pure water in DMSO, with LOD measured at 0.0067% v/v. The dissociation of OH- from D in the presence of water is responsible for the colorimetric and fluorometric responses.

Summary: A metal-organic framework (Co-L) based on a thiacalix[4]arene derivative was synthesized using the solvothermal method, and composite materials were prepared by mixing Co-L with reduced graphene oxide (RGO), multiwalled carbon nanotubes (MWCNT), and mesoporous carbon (MC). The Co-L@RGO(1:1) composite material showed the best electrocatalytic activity for chlorogenic acid (CGA) detection due to RGO's large specific surface area and the ability to form hydrogen-bonding with the oxide of CGA. The modified glassy carbon electrode (Co-L@RGO(1:1)/GCE) exhibited a low limit of detection and excellent selectivity, stability, and reproducibility for CGA detection.

Summary: In this study, a low-metal iron-supported catalyst (Fe20/NC-Mg) was reported for the efficient synthesis of quinoxaline compounds, using water as a solvent and without additional bases. The synergistic effect of FeNx site and Mg (OH)2 nanorods in the catalyst played a key role in achieving high yields (82-91%) in 16 examples. The gram-level synthesis and reusability of the catalysts after four cycles demonstrated its industrial application potential.
