Özet

The phenanthroimidazole derivatives are used in the drug industry in large scale. In this study four new phenanthroimidazole-imine derivatives were synthesized and their spectroscopic studies as well as their antioxidant behaviors were examined. Structural analyses were made by FT-IR, H-1-NMR, C-13-NMR, LC-MS spectroscopy techniques. UV-vis absorption and emission spectroscopy techniques have been used to determine the photophysical characteristics of four newly synthesized phenanthroimidazoles. The maximum absorption and emission wavelengths, molar extinction coefficients (epsilon), singlet energy levels (Es), Stokes' shift values (Delta lambda) of phenanthroimidazole-imine derivatives are given. Additionally, the antioxidant behavior of all compounds were investigated which the ascorbic acid used as standard molecule in present study.
