Özet:

 


In this study, UV-Vis and fluorescence properties of two iminooxime ligands and their complexes, which have been previously synthesized, were investigated. UV-Vis. spectrum of the HL, H2L'.H2O and their complexes were measured in chloroform and π→π*, n→π*, CT→M, d→d transitions were determined. Fluorescence properties of the complexes of HL and H2L'.H2O were studied at room temperature. Measurement results showed that all the complexes display intraligand (π→π*) fluorescence. The optical behavior of the complexes of HL and H2L'.H2O were investigated using optical reflectance and transmittance measurements. The optical band gaps, which turned out to depend significantly on the metal coordination were calculated by optical absorption method. The analysis of the optical absorption data revealed optical direct transition with band gaps of 3.8 - 4.1 for all of the complexes.

 

Key Words: UV-Vis. spectra, fluorescence properties, optical  and gaps
