摘　　要：A novel rare earth complex monomer Tb-Ca-PMDMBA（PMDMBA denotes pyromellitic dianhydride-modified 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.A novel rare earth complex monomer Tb-Ca-PMDMBA(PMDMBA denotes pyromellitic dianhydride-modified Bisphenol A epoxy acrylate resin) was synthesized for the first time as following procedure.

Secondly, the complex monomer Tb-Ca-PMDMBA was prepared by coordinating Tb^(3+), Ca^(2+) 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 Tb^(3+) ion under UV excitation. The fluorescence intensity depends on the content of Tb^(3+) and reaches maximum when the mole ratio of Tb to Ca is 2∶9.
