Structural characterization, luminescence and electrochemical properties of the Schiff base ligands

In this study, we prepared two Schiff base ligands N-(4-hydroxy phenyl)-2,4-di-methoxy benzaldimine (TS1) and N-(4-hydroxy phenyl)-2,5-di-methoxybenzaldimine (TS2) which were characterized by structural, spectroscopic and analytical methods. The ligands TS1 and TS2 were obtained as single crystals from ethanol solution. X-ray diffraction data for two compounds showed that the bond lengths are within the normal ranges. The electrochemical properties of the Schiff base ligands were studied in different solvents and at various scan rates. The luminescence properties of the ligands TS1 and TS2 in different solvents and at different pH values have been investigated. The results show that the ligands exhibit more efficient luminescence properties in CH3CN and n-butanol. (C) 2012 Elsevier B.V. All rights reserved.
