    Optical investigation of palladium(II) phthalocyanine including an aromatic group
    (Turkish Chemical Society, 2018) Özçeşmeci, İbrahim; Sorar, İdris
    Peripherally ?-naphthoxy-substituted palladium(II) phthalocyanine was synthesized from corresponding phthalonitrile compounds. The palladium(II) phthalocyanine was characterized with ultraviolet–visible spectroscopy (UV-Vis), fourier transform-infrared spectroscopy (FT-IR), mass spectrometry, and elemental analysis techniques. Thin films of palladium(II) phthalocyanine were prepared using different organic solvents by spin coating technique. Transmittance and absorbance spectra of the thin films were studied in the wavelength range of 200–1000 nm. Optical band gaps of palladium(II) phthalocyanine thin films were also calculated. © 2018, Turkish Chemical Society. All rights reserved.

    Synthesis and some optical results of long chain substituted phthalocyanines
    (2018) Özçeşmeci, İbrahim; Sorar, İdris
    Four metallo (zinc, copper, vanadyl, and indium) phthalocyanine derivatives bearing four aliphatic (hexylthio) groups were prepared from corresponding phthalonitrile compounds. The metallophthalocyanines were characterized with ultraviolet{visible spectroscopy (UV-Vis), proton nuclear magnetic resonance ( 1 H NMR), Fourier transform-infrared spectroscopy (FT-IR), and mass and elemental analyses techniques. Aggregation properties of metallophthalocyanines in solution were studied in varied concentration ranges. Thin lms of metallophthalocyanines were obtained by spin coating technique. Optical measurements showed that transmittance values of metallophthalocyanine thin lms obviously changed with respect to the metal ion in the phthalocyanines. Transmittance spectra of the phthalocyanines synthesized using different metal ions showed a variation of about 8% and 15% in transmittance spectra of the Q band region was obtained by mixing the two metal phthalocyanine (indium and zinc) solutions.
