A highly selective and sensitive half-salamo-based fluorescent chemosensor for sequential detection of Pb(II) ion and Cys

Insights into crystal structures, supramolecular architectures and antioxidant activities of self‐assembled fluorescent hetero‐multinuclear [Cu (II)‐Ln (III)] (Ln = La, Ce, Pr and Nd) salamo‐like complexes

“…The ligand H 2 L was synthesized according to the literature (Scheme ), [ 47 ] which was prepared by refluxing a mixture of the obtained above 2‐[ O ‐(1‐ethoxyamide)]oxime‐6‐methoxyphenol (455.0 mg, 2.0 mmol) and 3‐ethoxysalicylaldehyde (330.5 mg, 2.0 mmol) in ethanol (70 ml). The reaction mixture was heated to ca.…”

“…[ 13,14 ] In recent years, in the research and development of functional materials, the introduction of rare earth elements with unique 4f electronic layer structure and unique physical and chemical properties has been widely developed at home and abroad, and has made great progress, which have open novel possibilities for a broad range of advanced applications, such as electrochemistry, [ 15–18 ] supramolecular buildings, [ 2,19–23 ] catalysis fields, [ 24–26 ] magnetism, [ 27–31 ] biological systems, [ 32–34 ] chemical sensors, [ 35–40 ] luminescence materials, [ 41–45 ] and DFT calculations. [ 46–48 ] Recently, many novel structural 3d–4f complexes have been reported by using salen‐like and salamo‐like N 2 O 2 ‐donor ligands, which also attracted people's attentions. [ 5 ] Excessive accumulation of oxygen free radicals in the cells will have an adverse effect on the body, which is also one of the important factors leading to inflammation and aging.…”

Insight into Rare Structurally Characterized Homotrinuclear CuII Non-Symmetric Salamo-Based Complex

“…About The synthesis procedure of the non-symmetric salamo-derived ligand (H 2 L) could be found in Scheme 1. 2-[O-(1-ethyloxyamide)]oxime-2-naphthol and 1,2-bis(aminooxy)ethane were synthesized on the basis of similar approaches [20,50].…”

Insight into two unusual stable homomultinuclear copper (II)‐based bis (salamo)‐type complexes

“…[ 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.…”
