    Preparation of complexes of 1-amino-6,7-O-cyclohexylidene-4-azaheptane with transition metal acetates
    (Maik Nauka/Interperiodica/Springer, 2006) Öztirk, OF; Sekerci, M; Özdemir, E
    1-Amino-6,7-O-cyclohexylidene-4-azaheptane (L) has been synthesized starting from 1-chloro-2,3-O-cyclohexylidenepropane prepared by the reaction of epichlorohydrin with cyclohexanone, catalyzed by BF3OEt2, Complexes of this ligand with Co(II), Ni(II) and Cu(II) acetates were prepared. The structures of the ligand and its complexes are proposed based on the elemental analyses, IR, UV-VIS, and H-1 and C-13 NMR spectra, magnetic susceptibilities, and conductomety data.

    Synthesis of 5,6-O-cyclohexylidene-1-amino-3-azahexane and its Co(II), Ni(II), Cu(II) complexes
    (Pleiades Publishing Inc, 2005) Özturk, ÖF; Sekerci, M; Özdemir, E
    5,6-O-Cyclohexylidene-1-amino-3-azahexane (L) is synthesized from 1-chloro-2,3-0-cyclohexylidenepropane, which is prepared by the reaction between epichlorohydrin and cyclohexanone. In this reaction, (BF3OEt2)-O-. is used as a catalyst. Complexes of Co(II), Ni(II) and Cu(II) acetates with this ligand are prepared. The structures of the ligand and its complexes are proposed based on elemental analysis, IR and UV-VIS spectroscopy, magnetic susceptibility, conductometry, and H-1 and C-13 NMR spectroscopy.

    The determination of the optical constants of Cu(II) compound having 1-chloro-2,3-o-cyclohexylidinepropane thin film
    (Elsevier, 2004) Yakuphanoglu, F; Sekerci, M; Ozturk, OF
    This paper reports the optical properties of Cu(II) compound having 1-chloro-2,3-o-cyclohexylidinepropane thin film to determine optical constants (refractive index n, extinction coefficient k and dielectric constant e). The optical constants were calculated by using an optical characterization method. The optical band gap and Urbach parameter were determined from the optical spectra. The studies on the thin film revealed that the nature of electronic transition from valence band to conduction band was a direct transition. The exponential behavior of the absorption edge is attributed to the electronic transition in the localized states tailed off in the energy band gap. The spectral dependences of the optical constants show that both the refractive index and extinction coefficient are decreased with wavelength. The real and imaginary parts of the optical conductivity of the thin film were investigated and it is observed that the optical conductivity increases with frequency. (C) 2004 Elsevier B.V.
