Synthesis of new carbazolyl oxazolone derivatives and studying spectroscopic properties

Structures containing carbazole have great interest in various fields of technology because of their electrical, chemical, photo refractio, photoconductivity and shown II.order non-linear optical materials and optical properties. Krasovitskii and coworkers was the first group that sudied in the photophysical properties of oxazole-5-on derivates. In literature, many studies show that the oxazolone derivates can be used in semi conductive systems as electronegative photoreceptor in non-linear optical materials for its photochemical and photophysical properties. In the last years they have been used for photosensor in semi-conductive materials and photoreceptors.In this study, the newly sixteen carbazole derivates were synthesized. Aldehyde derivates was selected to examine its electron withdrawing and electron donating system and their effect when binding with glycine structure. The structure analysis and characterisation of synthesized compounds was cleared with fourier transform infrared and proton nuclear magnetic rezonance spectrocsophic techniques. The results of fourier transform infrared and proton nuclear magnetic rezonance spectrums were examined with the variation of the wave number and chemical shift of protons in N-carbozole glycine.For using of application in different areas of the synthesized compounds, UV-vis absorption and emission spectroscopic methods were studied and photophysical parameters were determined.Also, it is considered that the biologic active carbazole groups will affect the biological properties of synthesized azlactone derivates. For this reason, biological activation properties of oxazolone derivates will be studied.
