Sci Rep 2024; 14:14452.

Abstract
The development of flame-retardant materials has become an important research direction. For the past dozen years, researchers have been exploring flame retardants with high flame-retardant efficiency, low toxicity, less smoke, or other excellent performance flame retardants. Therefore, this work aimed to synthesize new cyclodiphosph(V)azane derivatives and their Cu(II) and Cd(II) metal complexes and investigated their potential applications as high flame-retardant efficiency. Various techniques were used to characterize the prepared ligand H2L and its metal complexes, including elemental analyses, mass spectra, conductivity measurements, electronic spectral data UV-vis, FT-IR, 1H,13C-NMR, TGA, XRD, and molecular docking experiments studies were M. tuberculosis receptors (PDB ID: 5UHF) and the crystal structure of human topoisomerase II alpha (PDB ID: 4FM9). Wood-based paint was physically mixed with the ligand H2L and its metal complexes. The obtained results of mechanical characteristics of the dried paint layers were noticed to improve, such as gloss value, which ranged from 85 to 95, hardness 1.5-2.5 kg, adhesion 4B to 5B, and impact resistance, which improved from 1.3 to 2.5 J. Moreover, the obtained results of flame-retardant properties showed a significant retardant impact compared to the blank sample, such as ignitability, which includes the heat flux which increased from 10 to 25 kW/m2, and ignition time, ranging from 550 to 1200 s, respectively, and limiting oxygen index (LOI) (%) which has been increased from 21 to 130 compared with the plywood sample and sample blank. The ordering activity of the observed results was noticed that coated sample based on Cd(II) metal complexes > coated sample based on Cu(II) metal complexes of Cyclophosphazene ligand > coated sample based on phosphazene ligand H2L > coated sample without additives > uncoated sample. This efficiency may be attributed to (1) the H2L is an organophosphorus compound, which contains P, N, Cl, and aromatic six- and five-member ring, (2) Cu(II) and Cd(II) metal complexes characterized by high thermal stability, good stability, excellent performance flame retardants, and wide application.

Abstract
AbstractGerms are transmitted in different ways and remain viable or infectious on metal, glass, wood, fabrics, and plastic surfaces for prolonged periods of time. Thus, sterilizing commonly handled everyday objects and public places with high contamination potential is a major global strategy to combat the spread of pathogenic microorganisms. Consequently, our response is development of durable surface‐active coating embedded with new Gd(I)/Cs(III) complexes that derived from condensation of thiocarbohydrazide and benzil precursors. Chemical structures of these complexes were elucidated by Fourier transform infrared (FTIR), electron impact ionization (EI‐MS), 1H nuclear magnetic resonance (NMR), elemental analysis, and scanning electron microscopy (SEM). Next, the well‐established complexes were physically mixed with wide‐range applicable polyurethane (PU) varnish as potential biocide agents. With laboratory scale, coating material was loaded into stainless steel and wood panels to evaluate the physical and mechanical properties. In comparison with the blank formulation, our additives enhanced the gloss levels of the developed PU from 75 to 80 gloss unit (GU), and the scratch hardness was increased to reach >2 kg. Meanwhile, all the coated films passed the flexibility bend test and showed none flaking in mechanical adhesion test. Consequently, Gd(I) and Cs(III) metal complexes did not show any undesirable side effects on PU coating performance. Concerning biological screening, macrocyclic Gd(I) and Cs(III) complexes as well as the reformulated PU varnish were assayed for their antibacterial, antioxidant, and antiviral activities. Antibacterial activity of the developed PU was slightly increased than the individual treatments of Gd(I)/Cs(III) complexes by 1–2 mm, although the blank PU showed no obvious activity against all the tested bacterial strains. Antiviral overall results indicated that the Gd(I) and Cs(III) complexes demonstrated higher activity than the developed PU samples against ADeno‐7, CV‐B4, and HSV‐1 viruses in all modes of action, and hence these coordinated compounds could be promising virucidal agents with good biocompatibility.

Abstract
AbstractManganese(ii) complexes of oxalic dihydrazones {N,N′-bis[2-hydroxynaphthylidene]amino]oxamide (BHO) and N,N′-bis[2-methoxybenzylidene]amino]oxamide (BMO)} have been synthesized by a general methodology. Hydrazone ligands (BHO and BMO) were obtained by the condensation of oxalic dihydrazide with 2-hydroxynaphthalene-1-carbaldehyde and 2-methoxybenzaldehyde. From the data obtained from the spectral (mass, IR, 1H-NMR, UV-Vis, ESR), magnetic and thermal measurements in addition to the elemental analyses (CHNM), the structures of ligands and their complexes have been determined. The scanning electron microscope (SEM) was used to characterize the morphology of the complex surface. The ligands coordinated with the metal center in a bi-dentate way forming binuclear Mn–BHO and mononuclear Mn–BMO complexes. The manganese complexes are proposed to have octahedral stereochemistry. The ligands and manganese(ii) complexes have been assessed for their antibacterial and antileukemia activities. The proliferation hindrance for the free ligands was enhanced upon coordination with the manganese(ii) ions.

Abstract
We reported here a new platform of supramolecular hydrogels cross-linked by the cooperation of metal-ligand coordination and hydrophobic interaction. A salicylaldehyde benzoyl hydrazone-terminal poly(ethylene glycol) (2SBH-PEG) was synthesized and formed small micelles in an aqueous environment. Addition of Ni2+ connected the low-molecular-weight 2SBH-PEG into a metallopolymer via metal-ligand coordination and led to micelle aggregation, resulting in gelation due to the enhancement of hydrophobic interaction. The forming hydrogel, Ni-PEGel, exhibited rapid self-healing ability and reversible pH-responsive property. Because of the containing metal coordination bond, it was also sensitive to the strong competing ligands, such as ethylenediaminetetraacetic acid (EDTA) and pyridine. In addition, Ni-PEGel showed colorimetric changes when exposed to biogenic amine (BA) vapor. The color development of Ni-PEGel toward BAs makes it a good candidate in monitoring food spoilage.
