Synthesis and Fluorescence Properties of the Ternary Complex of Praseodymium Chloride with Alanine and Imidazole

Alanine is an integral part of the organism.Imidazole is a large conjugated system.The rare earth coordination of the imidazole group can effectively absorb the light energy and pass energy to rare-earth ions.Therefore,the complex combining these three components has good luminescent properties.In this thesis,ternary complex of PrCl3·nH2O,alanine and imidazole was synthesized in the secondary water solvent.The chemical formula of this complex was determined by chemical analysis and elemental analysis.Its properties were characterized by IR,UV spectra,molar conductance measurements and fluorescence spectra.This paper discussed the interactions of the rare earth ion with imidazole and amino acid through the spectrum analysis of the complex,expecting to provide a theoretical foundation for the further study of the complex and rare earth elements in biological,physiological mechanisms and promote research in molecular fluorescence.
