A coordination polymer (PAA-Eu3+-DBM) was formed by the reaction of metallorganic complex (NaEu-(DBM)4) with polyacrylic acid (MW=5000).The coordination polymer
which is insoluble in most organicsolvents
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 Eu3+ 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.
