Catching S²⁻ and Cu²⁺ by a highly sensitive and efficient salamo-like fluorescence-ultraviolet dual channel chemosensor

Influence of structural variation of salamo‐based ligand on supramolecular architectures, Hirshfeld analyses, and fluorescence properties of new tetranuclear NiII complexes

“…[42][43][44] In addition, multinuclear metal complexes have potential applications in the field of coordination chemistry. [45][46][47][48][49][50][51][52] For decades, polynuclear complexes have attracted a remarkable attention. [53][54][55][56][57][58][59][60][61][62][63][64][65] This interest comes from various applications relative to different branches on natural combined sciences: chemistry, biology, and physics.…”

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

“…3424 cm −1 , this band were disappeared in the FT‐IR spectra of complexes 3 and 4 , which is indicative of the fact that the phenolic hydroxyl groups of the ligand H 2 L had been completely deprotonized and coordinated to the M (II/III) atoms. [ 22,35–37 ] Besides, complex 1 appeared at ca. 3410 cm −1 compared to the ligand H 2 L, the strong O–H stretching vibration absorption peak belongs to the O–H absorption peak on the free ethanol molecule, while the strong O–H stretching vibration absorption peak in complexe 2 were observed at ca.…”

“…[ 6–12 ] Rare earth, as an indispensable key material in modern society, has attracted more and more attention due to its scarcity of output and value. [ 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.…”

Investigation of mononuclear, dinuclear, and trinuclear transition metal (II) complexes derived from an asymmetric Salamo‐based ligand possessing three different coordination modes

“…[1][2][3][4][5] Salen-based compounds have four coordination atoms (O, N, N, and O) in the center and can be coordinated with various metal ions to form M-Salen complexes. [6][7][8] The structure of N and O coordination with metal ions of Salen complexes, [9][10][11][12] which is close to the biological environment, [13][14][15][16] has attracted considerable attention in the field of molecular recognition. [17,18] In addition, M-Salen complexes have been widely used in various catalytic reactions due to their important and interesting structures, [19][20][21][22] variable, simple synthesis route, and easy recycling of catalysts.…”
