Two constitutional dynamic libraries (CDLs) - each containing two amines, two dialdehydes, and two metal salts - have been found to self-sort, generating two pairs of imine-based metallosupramolecular architectures (sharing no component) each with a [2 ×

In order to model the syn disposition of histidine residues in carboxylate-bridged non-heme diiron enzymes, we prepared a new dinucleating ligand, H2BPG2DEv, that provides this geometric feature. The ligand incorporates biologically
Enhancement of 4-electron O2 reduction by a Cu(II)-pyridylamine complex via protonation of a pendant pyridine in the second coordination sphere in water

We have synthesised a novel copper(II) complex with a pyridine pendant as a proton relay port for electrocatalytic 4e- reduction of O2 in water. The enhancement of the electrocatalytic O2 reduction via protonation of the pyridine pendant is demonstrated in comparison with a copper(II) complex without the pyridine pendant.

Synthesis of new Schiff's base Zn-complexes for photo-oxidation of methyl arenes and xylenes are reported under visible light irradiation conditions. All the synthesized new ligands and Zn-complexes are thoroughly characterized with various spectral analyses and confirmed as 1:1 ratio of Zn and ligand with distorted octahedral structure. The bandgap energies of the ligands are higher than its Zn-complexes. These synthesized new Zn(II) complexes are used for the photo-fragmentation of organic dye pollutants, photodegradation of food industrial wastewater and oxidation of methyl arenes which are converted into its respective aldehydes with moderate yields under visible light irradiation. The photooxidation reaction dependency on the intensity of the visible light was also studied. With the increase in the dosage of photocatalyst, the methyl groups are oxidized to get aldehydes and mono acid products, which are also identified from LC-MS data. Finally, [Zn(PPMHT)Cl] is with better efficiency than [Zn(PTHMT)Cl] and [Zn(MIMHPT)Cl] for oxidation of methyl arenes is reported under visible-light-driven conditions.
