Aggregation-induced emissive pyridoxal derived tetradentate Schiff base for the fluorescent turn-off sensing of copper(II) in aqueous medium

In this study, a tetradentate Schiff base ligand L was synthesized by condensing o-phenylenediamine with two moles of pyridoxal. The solution of L in EtOH/DMSO showed aggregation-induced emission (AIE) behaviour...

Large interaction energy for the homodimer and the heterodimer extracted from the supramolecular chain of a bent trinuclear zinc(II) complex with a reduced Schiff base ligand

A bent trinuclear zinc complex, [Zn{ZnIL}2]•DMF {H2L = 2,2'-[(2,2-Dimethyl-1,3-propanediyl)bis(iminomethylene)]bis[6-methoxyphenol]} was synthesized and characterized by standard spectroscopic methods and X-ray diffraction analysis. The existence of coordinated amino groups and iodide counter...

Toroidal magnetic moments in Tb4 squares

A series of Tb4 complexes isolated from reduced or dimerized Schiff base ligand share a similar µ4-O bridged Tb4 square core with the magnetic moments of the TbIII ions in...

Design and construction of an electrochemical sensor for the determination of cerium(iii) ions in petroleum water samples based on a Schiff base-carbon nanotube as an ionophore

A carbon paste and screen-printed sensor for Ce(iii)-selective determination were prepared using a 2,6-pyridine dicarbomethine-triethylene tetraamine macrocyclic Schiff base ligand and multi-walled carbon nanotubes as good sensing materials.
