| Abstract: | A novel rare earth complex monomer Tb-Ca-PMDMBA(PMDMBA denotes pyromellitic dianhydridemodified Bisphenol A epoxy acrylate resin)was synthesized for the first time as following procedure.Firstly,Bisphenol A epoxy acrylate resin and Bisphenol A epoxy acrylate resin modified with pyromellitic dianhydride were synthesized from Bisphenol A epoxy resin,acrylic acid and pyromellitic dianhydride through esterification respectively.Their composition is ascertained by the analysis of acidic value and FTIR spectrum.Secondly,the complex monomer Tb-Ca-PMDMBA was prepared by coordinating Tb3+,Ca2+ with carboxyl groups,and then its fluorescence properties were investigated.The results show that Tb-Ca-PMDMBA complex can emit intense characteristic emission spectrum of Tb3+ ion under UV excitation.The fluorescence intensity depends on the content of Tb3+ and reaches maximum when the mole ratio of Tb to Ca is 2:9. |
