| Abstract: | A coordination polymer (PAA Eu 3+ DBM) was formed by the reaction of metallorganic complex (NaEu\|(DBM) 4) with polyacrylic acid ( M w=5000).The coordination polymer, which is insoluble in most organic solvents, is a white solid and can be soluble in the mixed solvent of glyceryl alcohol and isopropanol.The polymer was characterized by FT IR, UV, electrical conductivity methods, elemental analysis, fluorescence spectrum, and its composition and structure were determinated.The rusult indicated that each Eu 3+ ion is coordinated by one DBM molecule and two carboxyl units of the PAA molecules.The fluorescence spectrum indicated that the coordination polymer has good fluorescence properties. |
