Summary: This paper presents a novel ultrasensitive simultaneous detection procedure for heavy metals (HMs) lead, cadmium, and mercury using a Fe-Al MMON on glassy carbon electrode. The Ch-MMON/GCE electrode showed excellent sensitivity with detection limits well below WHO permissible limits, especially with the DPV method. The proposed method could accurately measure HMs in river water, demonstrating significant performance and reliability.

Summary: In the synthesis of a trinuclear Cd(II) complex with tris(2-aminoethyl)amine ligand, spontaneous atmospheric CO2 capture as carbonate anion occurred. Two types of compounds were obtained and structurally characterized by X-ray diffraction, with the carbonate anion partially replacing the bridging tren molecule and coordinating in a μ(3) fashion. The luminescent properties of the compounds were investigated.

Summary: A pair of chiral cages were self-assembled using symmetric chiral ligands, and could be downsized with the presence of hydrochloric acid. The original cages showed better enantioselectivity for chiral recognition, while the downsized cages exhibited significant recognition of chiral molecules through photoluminescence.

Summary: Ten coordination compounds were isolated from reactions of divalent metal ions (Cu-II, Ni-II, and Zn-II) with the Schiff base ligand H2L derived from salicylaldehyde and omega-hydroxy carbonic acid hydrazide. The protonation levels of the ligand significantly influenced the coordination conformations of the metallosupramolecular compounds in the solid state. The structures of various complexes, including monomeric and dimeric compounds, were elucidated using single-crystal X-ray diffraction.

Summary: Fe(II) and Ni(II) paraCEST contrast agents containing di-pyridine macrocyclic ligand were synthesized and characterized. Their structures were determined by crystallography, and their CEST contrast effects were studied at body temperature. The protonation constants and thermodynamic stability constants were determined as well.

Summary: Combining photodynamic therapy with chemotherapy using new dithiocarbazate-Zn(ii) complexes shows promising results for the treatment of lung cancer. The complex Zn3 exhibits good chemotherapeutic ability and generates superoxide anion radicals under light irradiation, leading to cancer cell death through photodynamic therapy. This study provides new strategies for multimodal cancer therapy.

Summary: This study evaluated the phytoremediation potential of Clidemia sericea for soils contaminated with PTEs from gold mining activities. The results showed that C. sericea has the potential to stabilize mercury and cadmium in mining soils, with little phytotoxic effects on plant growth and development in different treatments.

Summary: The properties of Ln(3+) complexes with bifunctional ligands were studied, showing differences in stability, kinetics, and structure, making them suitable for MRI contrast agents. The stability constants of DO3A-BACE(4-) complexes vary with different Ln(3+) ions, and they exhibit a certain level of inertness compared to other complexes.

Summary: This work reports the synthesis, structural and photo-physical characterization of six phosphorescent H2O-soluble Pt(II) complexes with different ancillary ligands, evaluating their potential as switch-on-photoluminescent labels for specific biofilm sensing. The study reveals that selected complexes can interact specifically with biofilms, offering a novel platform for early detection of bacterial arrays in complex environments.

Summary: This study demonstrated that Cu(II) can competitively exchange with Hg(II) when bound to CYS, GSH, or DOM, while Zn(II) and Ca(II) do not have the same effect. Additionally, EDTA can facilitate the exchange of Hg(II) by Cu(II), Zn(II), and Ca(II).

Summary: In this study, a series of Zn(II) and Cd(II) metal complexes were synthesized using various unsymmetrical aryl thiourea ligands. The ligands and metal complexes were characterized by H-1, C-13{H-1} NMR and FT-IR analysis. The solid-state structures of the zinc and cadmium metal complexes were determined by single-crystal diffraction analysis. Furthermore, the catalytic activities of the Zn(II) complexes towards the hydroboration of aldehydes and ketones were studied, and excellent yields of the corresponding boronate esters were achieved.

Summary: This study focuses on the synthesis, structural, and photophysical characterization of platinum dihalogenide complexes with different 10-(aryl)phenoxarsine ligands. The structures of the complexes were determined using various techniques, with the cis/trans isomerism in solution studied using NMR spectroscopy. In the solid state, platinum diiodide trans complexes exhibited intense orange-red emission under UV irradiation, which was attributed to a metal halide-centered triplet state. The UV/vis absorption and emission properties were rationalized through density functional theory (DFT) and time-dependent DFT calculations.
