“…[ 53,56 ] Under the same conditions, the emission peaks of complexes 1 and 2 appear at approximately 475 and 488 nm, which is hypsochromic relative to H 3 L. Complexes 1 and 2 showed strongly fluorescence quenching, but the shape and position of the emission band remain unchanged, which may be caused by the ligand to the metal charge transfer transition (LMCT).

“…[ 26–30 ] A variety of 3d, 3d‐s, and 3d‐4f metal complexes and coordination polymers have been developed by using multidentate salamo‐type ligands. [ 31–43 ] Now, the synthesis of superior properties, structurally specific of salamo‐type chelate ligands, [ 44,45 ] metal complexes, [ 46,47 ] molecular probes, [ 48–56 ] and exploration of their application has become an extremely important field of chemistry. In the field of salamo‐type ligands and their corresponding macrocyclic and acyclic complexes, [ 57–59 ] Nabeshima et al have made a lot of prominent pioneering works by taking advantage of building blocks and metal spontaneous formation of metal‐ligand bonds.…”

Using symmetrical bis (salamo)‐type tetraoxime ligand H3L and Cu (ClO4)2·6H2O in different solvent systems, two unusual homomultinuclear Cu (II) complexes, [Cu4(L)2(CH3CH2OH)2](ClO4)2·2H2O (1) and [Cu2(L)]n (ClO4)n·nCH3CN (2), were synthesized and characterized by single‐crystal X‐ray diffraction analyses, elemental analyses, infrared (IR), ultraviolet–visible (UV–Vis) spectroscopy, Hirshfeld surfaces analyses, and density functional theory (DFT) calculations. Complex 1 includes [Cu4(L)2(CH3CH2OH)2]2+ ion, two ClO4− counter anions, two coordinated ethanol molecules and two aquatic dissociative molecules, the two deprotonated ligand (L)3− units package around four Cu (II) ions yield a centrosymmetric helical molecules with a charged linear folding center, while complex 2 forms a 1‐D linear topology structure and is only the substitution of chloroform in the solvent system of complex 1 with acetonitrile. Coordination mode of complex 2 is widely different from that of complex 1. In the Cu (II) ions of complex 1, there are two coordination modes of Cu (II) ions, the hexa‐coordinated distorted octahedral structure and the penta‐coordinated distorted tetragonal pyramid structure, but complex 2 only has almost perfect tetragonal pyramid geometry. Fluorescence properties of H3L and its complexes 1 and 2 have also been explored.

“…The ability of implant surface to improve the nucleation and growth of bone-like hydroxyapatite upon immersion in SBF is a common method to evaluate the bioactivity and osteoconductivity of the surface [51]. The 3BG/GE/PCL samples were soaked in SBF solution for various times to investigate the hydroxyapatite formation on the coated samples.…”

In this study, various composites of bioglass/gelatin/polycaprolactone (BG/GE/PCL) were produced and coated on the surface of 316L stainless steel (SS) to improve its bioactivity. X-ray diffractometry (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) were utilized to characterize the specimens. The results showed that bioglass particles were distributed uniformly in the coating. By increasing the wt.% of bioglass in the nanocomposite coatings, the surface roughness and adhesion strength increased. The corrosion behavior of GE/PCL (PCL-10 wt.% gelatin coated on 316L SS) and 3BG/GE/PCL (GE/PCL including 3 wt.% bioglass coated on 316L SS) samples were studied in PBS solution. The results demonstrated that 3BG/GE/PCL sample improved the corrosion resistance drastically compared to the GE/PCL specimen. In vitro bioactivity of samples was examined after soaking the specimens for 7, 14 and 28 days in simulated body fluid (SBF). The results showed a significant apatite formation on the surface of 3BG/GE/PCL samples. The cell viability evaluation was performed using 3- (4, 5-dimethylthiazol-2-yl)-2,5 diphenyltetrazoliumbromide (MTT) tests which confirmed the enhanced cell viability on the surface of 3BG/GE/PCL samples. The in vivo behavior of specimens illustrated no toxicity and inflammatory response and was in a good agreement with the results obtained from the in vitro test.

“…The salamo-based ligands with strong stability and multifunctional chelating ability have also been studied as a significant class of organic compounds containing N 2 O 2 -donor groups [12][13][14][15][16][17][18]. When compared with salen-based ligands, the salamo-based compounds and their complexes have been applied to ion recognition [19,20], optics [21], electrochemistry [22], magnetism [23,24], biochemistry [25,26], catalysis [27,28], supermolecular construction [29,30], and other fields [31][32][33][34][35][36][37][38], which are expected to give the salamo-based ligands and their derivatives good development potential to become one of the new research hotspots of coordination chemistry.…”

A rare homotrinuclear CuII salamo-based complex [Cu3(L)2(μ-OAc)2(H2O)2]·2CHCl3·5H2O was prepared through the reaction of a non-symmetric salamo-based ligand H2L and Cu(OAc)2·H2O, and validated by elemental analyses, UV-Visible absorption, fluorescence and infrared spectra, molecular simulation and single-crystal X-ray analysis techniques. It is shown that three CuII atoms and two wholly deprotonated ligand (L)2− moieties form together a trinuclear 3:2 (M:L) complex with two coordination water molecules and two bi-dentate briging μ-acetate groups (μ-OAc−). Besides, the Hirshfeld surface analysis of the CuII complex was investigated. Compared with other ligands, the fluorescent strength of the CuII complex was evidently lowered, showing that the CuII ions possess fluorescent quenching effect.
