dc.description.abstractHerein, we describe the synthesis and characterization of two novel tridentate ONN donor ligands, namely, (E)-2-(((2-(dimethylamino)ethyl)imino)methyl)-6-methoxyphenol (HL1) and (E)-2-(((2-(dimethylamino)ethyl)imino)methyl)-6-ethoxyphenol (HL2), and their copper(II) complexes, [Cu-2(L-1)(2)(CH3COO)(2)] (1), [Cu(L-2)(CH3COO)]center dot 2H(2)O (2). They have been synthesized under conventional methods and characterized by elemental analysis, FT-IR, H-1 NMR, C-11 NMR, ICP-OES, TGA, DSC and GC/MS analysis. For the morphological analysis field emission scanning electron microscopy (FESEM) was used. The geometry of the Cu(II) complexes was determined by single crystal X-ray diffraction analysis. The Cu(II) ions are in distorted square-pyramidal coordination environments. 1 crystallizes in orthorhombic space group, Pbca, while 2 crystallizes in monoclinic space group, P2(1)/c. Effects of different solvents and concentrations on the photoluminescence properties of the 1-2 were investigated. The emission bands bathochromically shifted due to increase of the dipole moments of EtOH to H2O and CHCl3 to DMSO, respectively. As a result of the dynamic quenching, the intensity of 1 was decreased with increasing the concentration in the water. The electrical conductivity complexes 1-2 have been also investigated.
