The Molecular Design,Synthesis And Performance Research Of Rich N-heterocyclic And Actinide Compounds

Nitrogen heterocyclic compounds are widespread in nature,and the researchers pay an attention to them because of they have multiple distribution sites and the good biological activity.In these compounds,triazole and tetrazole become the focus of research in recent years.With the uranium atom coordination forming urayl compounds,which have potential application in photochemistry,dyes adsorption,ion exchange,proton conductivity and photocatalysis.In this work,we synthesized two triazole and two tetrazole compounds through references.They are characterized by IR spectra,UV-vis spectra,1H NMR and 13C NMR.In the same time,we also explored fluorescence performance for them.Then with triazole,tetrazole and aromatic carboxylic as ligands,uranyl acetate as metal source,to synthesis nine uranyl complexes,which were characterized by X-ray single crystal diffraction,elemental analysis,IR spectra,UV-vis spectra,thermogravimetric analysis and X-ray powder diffraction.In addition,their photo luminescent,surface photovoltage properties as well as dyes adsorption properties have been studied firstly.Through the experiment we found that some complexes have good optical performance and dyes adsorption performance.Note:H2pht=phthalic acid;H2ipa=isophthalic acid;H2tpa=terephthalic acid;Hbox=benzoic acid; hpac=nicotinic acid;H6TTHA=1,3,5-triaziNe-2,4,6-triamine hexaacetic acid;DMF= N,N-dimethyl formamide;Li=5-methyl-1-(4-carboxylphenyl)-1H-1,2,3-triazole-4-carboxylic acid.
