Abstract

The thio Schiff base ligand N,N′-bis(o-hydroxy-1-naphtaldehydene)-1, 2-bis(o-amino phenilthio)ethane (L) was synthesized by the condensation of o-hydroxy-1-naphthaldehyde and 1,2-bis(2-amino thiophenol)ethane. The reactions of the ligand with different transition metal(II) salts under reflux system condition afforded a series of metal complexes such as Cu(II), Co(III), Ni(II) and Pd(II). Ligand and its complexes were characterized by a combination of elemental analysis, UV-vis spectroscopy, FT-IR, 1H NMR, MS and TGA/DTA. The electrochemical properties of L and [Cu(L)] were investigated using cyclic voltammetry (CV) in the solutions of dimethyl sulfoxide (DMSO). The catalytic property of thio Schiff base ligand with Suzuki cross-coupling reactions were also determined with different substituted aryl halides in the presence of aryl boronic acid and Pd(AcO) 2 as catalyst. In addition, the fabrication of organic-inorganic hybrid devices using L and its Co(III), Ni(II) and Pd(II) complexes and their electrical properties have been reported.
