Cd-Based metal-organic frameworks from solvothermal reactions involving in situ aldimine condensation and the highly sensitive detection of Fe3+ ions

Four Cd(ii)-based compounds (1-4) were synthesized from solvothermal reactions involving the in situ aldimine condensation of an o-diamino-functionalized precursor 3,6-di(4H-imidazol-4-yl)benzene-1,2-diamine (L), Cd(NO₃)₂·4H₂O and aldehyde. Two modes of cycloaddition ([4 + 1] cycloaddition and [4 + 2] cycloaddition) occurred during condensation, causing the in situ generation of two benzimidazole derivative ligands (L1 and L3) and a quinoxaline derivative ligand (L2). Furthermore, the chemical selectivity of the condensation was studied, where the condensation of o-diamino and the aldehyde is more stable and easy to operate. This strategy enriches the synthesis method of MOFs. Additionally, compound 2 containing uncoordinated quinoxaline N atoms showed excellent luminescent sensitivity for Fe³⁺ detection.

Two cationic [(CuxIy)x−y]n motif based coordination polymers and their photocatalytic properties

Two cationic [(Cu_xI_y)^x−y]_n based coordination polymers, featuring a 3,6-connected net or a coordination chain, and interesting supramolecular structures, exhibit photochemistry properties towards degradation of methyl blue.

Dicarboxylate ligand-modulated assembly of new luminescent zinc(ii) coordination polymers with in situ formed tetrazole ligands: an experimental and theoretical study

In situ hydrothermal reactions of 4-(1H-imidazol-1-yl)benzonitrile, Zn(NO₃)₂ and NaN₃ with H₂DPA or H₂PYDC gave rise to two new zinc(ii) coordination polymers, which exhibit different intriguing architectures and photoluminescence properties.

Can a highly flexible copper(i) cluster-containing 1D and 2D coordination polymers exhibit MOF-like properties?

The p-TolS(CH₂)₈STol-p and p-tBuC₆H₄S(CH₂)₈SC₆H₄-tBu-p ligands react with CuI respectively in MeCN and EtCN and in EtCN form the 2D and 1D polymers [Cu₈I₈(p-TolS(CH₂)₈STol-p)₃(solvent)₂]_n (solvent = MeCN, EtCN) and [Cu₄I₄(p-tBuC₆H₄S(CH₂)₈SC₆H₄-tBu-p)₂(EtCN)]_n susceptible to exchange solvent molecules.
