Synthesis And Characterization Of Coordination Polymer Of Eu(Ⅲ) Polypropylene Acid And Polyarcylamid

The synthesis , characterization and properties of the Eu(Ⅲ) complexes of polycarboxylic acid, polyacrylamide, acetaacetone- polycarboxylic acid , have been studied in this thesis. Three kinds of typical polymer ligands of polycarlic acid(PAA) and polyacetamide(PAM) have been synthesized, and a detailed investigation on the formed coordination compounds with rare earth metals has been carried out as well.This paper consists of five parts as follow:1. A brief review of the study for macromolecular metal complexes compounds and low temperature solid phase reaction have been given.2. polyacrylic acid ligand was synthesized ,their compounds with rare earth nitrates have been synthesized and characterized. The scheme of polyacrylic acid ligand are showed as follow: The component and the scheme of Eu-PAA are showed respectively as follow: The carboxylates maybe are in the same chain or not.3. Another polymer polyacetamide(PAM) and its compounds with Eu have been synthesized and characterized. The molecular formula of Eu-PAM are showed respectively as follow: All these compounds have been characterized by elemental analysis, IR spectra, fluorescent spectra, TG-DTA. The results show that the ratio of–COO-:Eu(Ⅲ) is almost 3:1,the ratio of–CONH2-:Eu(Ⅲ) is almost 6:1. They all have typical structure and the emission intensity of fluorescence of these compounds is stronger than that of simple rare earth compounds.4. Eu-PAA-acac has been synthesized and characterized. The component of the Eu-PAA-acac is:The compound has been characterized by elemental ,UV spectra, IR spectra, conductance ,TG-DTA., Fluorescent.. the result shows that the production has fixation compose when add Eu (Ⅲ) and small molecule into polycarboxylic acid after all these have reaction. The production is a good irradiance material.The outcome shows that the rare earth cordination polymers which have been synthesized have steady compose , are unsolvable in most organic solvent and have high decomposed temperature and excellent fluorescence property.5.conclusion and constructionIntroduce the thesis'content and provide some construction.
