Solid phase coordination reaction of Sm3+ and the resultant of the imidization of polycondensor of polycondensation and imidization of benzoguanamine(BGA) and 2, 4-tolylenediisocyanate (TDI) and pyromellitic dianhydride (PMIDA) under microwave irradiation were synthesized and studied. The effect of microwave irradiation time (power), the composition of reactants and the reaction temperature on the yield and Sm content in complexes were studied. The complex was determined by Fourier transform infrared absorption (FTIR), Fourier transform Roman spectrum (FTRS), scanning electric minor (SEM), 13C solid state nuclear magnetic resonance spectrometry and X-ray powder diffraction. The fluorescence intensity was measured by fluorescent emission spectrum and compared with thermal coordination. The magnetic susceptibilities were measured by magnetic curve. The results showed that the complex had not characteristic fluorescence of Sm3+, which illustrated that the first excitation level of Sm3+ and polymer could not match at all. But the complex showed good magnetic property of the ion.
合成并研究了微波辐射下Sm3+的固相配位反应以及苯并胍胺（BGA）与2,4-甲苯二异氰酸酯（TDI）和均苯四甲酸二酐（PMIDA）缩聚及亚胺化产物。研究了微波辐射时间（功率）、反应物组成和反应温度对配合物产率和Sm含量的影响。通过傅里叶变换红外吸收（FTIR）、傅里叶变换拉曼光谱（FTRS）、扫描电子显微镜（SEM）、13C固态核磁共振光谱和X射线粉末衍射对配合物进行了表征。通过荧光发射光谱测量荧光强度并与热配位进行比较。通过磁曲线测量磁化率。结果表明，该配合物没有Sm3+的特征荧光，这说明Sm3+的第一激发态与聚合物根本不匹配。但该配合物显示出良好的离子磁性。
