Synthesis, Characterizations and Luminescent Properties of Two Cadmium(II) Coordination Polymers Derived from Bis(Benzimidazole)-Based Ligands

Structural modulation of Co(II) coordination polymers with flexible bis(benzimidazole) and different dicarboxylate ligands

“…The rational design and synthesis of novel metal-organic frameworks (MOFs) is currently attracting considerable attention because of their fascinating topological structures and potential applications as functional materials in porosity, catalysis, luminescence, conductivity, magnetism, and so on [1][2][3][4][5][6]. From a synthetic point of view, the judicious selection of appropriate organic ligands is proved to be one of the most effective ways to manipulate the diverse structures of MOFs.…”

Thermostability and photophysical properties of mixed-ligand carboxylate/benzimidazole Zn(II)-coordination polymers

“…A mixture characteristics of intraligand and ligand-to-ligand charge transition (LLCT) has already been reported for other Zn(II) complexes based on N-donor and O-donor ligands [12,46]. However, as both profiles of emission bands of (1) and (2) are similar to that obtained for the free ligand benzimidazole, therefore, the luminescence properties of these samples may be attributed mainly to the benzimidazole ligand [14].…”

Synthesis, crystal structures, luminescence and catalytic properties of two d10 metal coordination polymers constructed from mixed ligands

“…The emission with maxima at 390 nm for 1 (k ex = 240 nm), 400 nm for 2 (k ex = 260 nm), respectively. The emission band of 1 and 2 are similar to the free bmb ligand, which is neither metal-to-ligand charge transfer (MLCT) nor ligand-tometal charge transfer (LMCT) in nature [32]. Thus, the emission may be assigned to the transitions of N-donor ligand.…”
