EXAMINATION OF FLUORESCENCE PROPERTIES OF IMIDAZOLE AND SCHIFF BASE LIGANDS DERIVED FROM 1,10-PHENANTHROLINE

Abstract

Time Resolved Emission Spectra (TRES) of newly synthesized a Schiff base and an imidazole ligands both derived from 1,10-phenantroline were obtained with PTI Time Master C71 model spectrofluorometer and were calculated their fluorescence lifetimes. Optimum solvent and concentration in which the fluorescence properties of each ligands were observed the best were determined. Ethanol, methanol, dimethylsulfoxide ( DMSO) and chloroform were used as solvents. As a result of several experimenrts optimum fluorescence emissions of the ligands were obtained in DMSO and chloroform, It was found that the optimum interval of concentration was between 1.10(-4) M and 1.10(-5) M. The fluorometric data showed that the ligands could be used for determination of markable quantities of the ions, Ni2+, Cu2+ and Co2+.
