    Photovoltaic, thermal, fluorescence and aggregation properties of non-peripherallyvmetallophthalocyanines bearing four 3,4-dimethoxyphenethoxy substituents
    (2020) Solğun, Derya Güngördü; Ağırtaş, Mehmet Salih; Horoz, Sabit
    In this study, a non-peripheral phthalonitrile compound was prepared as a starting material. Then this 3,4- dimethoxymethoxy substituted non-peripheral phthalonitrile compound was reacted with Co, Zn and Cu salts. Nonperipheral phthalocyanine compounds were prepared using an easy and practical method. The fluorescence spectra of the zinc phthalocyanine compound were measured in tetrahydrofuran. Aggregation studies showed the compliance with the lambert-beer law in the concentration range studied for non-peripheral phthalocyanine compounds. Thermogravimetric (TG) analyses showed that the compounds were stable. The photovoltaic performance of these phthalocyanine compounds was measured as current densityvoltage (J-V). The calculated power conversion effects showed that these compounds had the potential to be used for dye-sensitized solar cell (DSSC) structures.

    Preparation of Metal Complexes of 4,5-Dichlorphthalic Acid as Nanoscale and Electronic Properties
    (2020) Keskin, Mehmet Salih; Yıldıko, Ümit; Solğun, Derya Güngördü; Ağırtaş, Mehmet Salih
    Here phthalic acid metal complexes with acid function were synthesized. Fourie transform infrared spectroscopy (FT- IR), X-ray diffraction analysis (XRD), Scanning electron microscopy-Energy Dispersive Spectrometry (SEM+EDS) devices were used for structure analysis. The structural parameters of the copper and zinc complexes of 4,5-dichlorphthalic acid were determined by the LanL2DZ basis base set of B3LYP method. Electronic properties such as HOMO (highest occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) energies and molecular electrostatic potential (MEP) were obtained. Stability, charge delocalization of molecules resulting from hyperconjugative interactions were analyzed using natural bond orbital (NBO) analysis. The comparison of the theoretical and experimental FT-IR spectra of Zn and Cu-4,5-dichlorphthalic acid (DCPA) were made and R = 0.97204 for Cu and R = 0.97929 for Zn complex were found in linear fit studies. Two characterization results were found to be consistent.
