Fluorescence Properties in Different Solvents and Synthesis of Axially Substituted Silicon Phthalocyanine Bearing Bis-4 Units
(Walter de Gruyter Gmbh, 2020) Agirtas, Mehmet Salih
In this present study, a new axially bis-4-tritylphenoxy substituted silicon phthalocyanine compound was synthesized and characterized using infrared, mass, electronic absorption and nuclear magnetic resonance spectroscopy. Fluorescence and absorption spectra studies of the disubstituted silicon phthalocyanine complex were conducted on the chloroform, dimethyl formamide, dimethyl sulfoxide and tetrahydrofuran solutions. The findings of the fluorescence studies demonstrated that the compound has fluorescence spectra in the different solvents. The effects of the substitution with axially bis-4-tritylphenoxy functionalized groups on these parameters were also compared with the previously synthesized axially disubstituted silicon phthalocyanines. These results proved that the compound has different fluorescence properties in the different solvents.
A New Method for the Reaction of Cross-Coupling: Preparation of 5,5'-bi(1,10-phenanthroline)
(Walter de Gruyter Gmbh, 2017) Agirtas, Mehmet Salih
Synthesis and characterization of 5,5'-bi(1,10-phenanthroline) (3) are described. Compound 3 was obtained by treatment of 5-chloro-1,10-phenanthroline (1) with 4-hydroxy-phthalonitrile (2) in the presence of K (2) CO (3) as a base in DMF at room temperature for 25 h.
