Synthesis, Characterization And Fluorescenc Of β-DIKETONE Complexes

In this thesis, a seriesβ-diketone(2,5-dihydroxycyclohexa- 1,4-diene-1,4-dicarboxylate) derivatives are synthesized. We utilize the known structural compounds including N and O to coordinate to metallic ion. The structures from X-ray single crystal diffraction are utilized to search for the relationship between structure and function. My work is summarized as follows:1. Series ofβ-diketone derivatives are synthesized. Their structures were confirmed with 1H NMR and IR .And the crystal structures of three building blocks are determined by X-ray single crystal diffraction. Their crystal structures are studied at microstructure. And the environment of atomic arrangement and molecular accumulation were analyzed through correlation software. And their optical physical properties were mensurated and analyzed.The synthesis method ofβ-diketone derivatives, we conclude a best synthetic route of reaction by utilizing different catalyzer, solvent and temperature of the reaction.2. Someβ-diketone derivatives have been synthesized by coordinating to metallic ion.Optical physical properties of them were mensurated and analyzed, respectively. Through comparison, we have searched for the relationship between structure and function.3. From thermodynamics, quantum chemical calculations were performed with GAUSSIAN 03 program. We determine the below reaction possible at room condition. Therefore, we conclude a kind of reaction feasible.
