    Novel copper(II) complexes of two tridentate ONN type ligands: Synthesis, characterization, electrical conductivity and luminescence properties
    (Elsevier Science Sa, 2018) Gonul, Ilyas; Burak, A. Y.; Karaca, Serkan; Sahin, Onur; Serin, Selahattin
    Herein, 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.

    Synthesis, characterization, electrical conductivity and luminescence properties of two copper(II) complexes with tridentate N2O chelating ligands containing imine bond
    (Elsevier Science Bv, 2018) Gonul, Ilyas; Ay, Burak; Karaca, Serkan; Sahin, Onur; Serin, Selahattin
    In the present study, we describe the synthesis and characterization of two tridentate N2O donor ligands, namely, (E)-2-(((2-(diethylamino)ethyl)imino)methyl)-6-methoxyphenol (HL1) and (E)-2-(((2-(diethylamino)ethyl)imino)methyl)-6-ethoxyphenol (HL2), and their copper(II) complexes, [Cu(L-1)(CH3COO)] (1), [Cu(L-2)(CH3COO)] (2). They have been synthesized under conventional methods and characterized by elemental analysis, FTIR, H-1 and C-13 NMR, ICP-OES, TGA and GC/MS analysis. For the morphological analysis field emission scanning electron microscopy (FESEM) was used. The geometry of the copper(II) complexes was determined by single crystal X-ray diffraction analysis. The copper(II) ions are in distorted square-pyramidal coordination environments. Complexes crystallize in monoclinic space group, P2(1)/c. The electrical conductivity and luminescence properties of 1-2 have been investigated. (C) 2017 Elsevier B.V. All rights reserved.
