【摘要】 在N2气保护下,将有机配体HTTA(α-噻吩甲酰三氟丙酮)引入三异丙氧基稀土中,合成了具有一定配位作用的铕、铽、钐稀土配合物(Re(OPri)(TTA)2),并与MMA单体通过本体聚合制备配位键合Re(OPri)(TTA)2的有机玻璃材料,用元素分析、FT-IR、XRD、FS等测试技术对其进行了表征。结果表明,含铕、铽或钐稀土配合物Re(OPri)(TTA)2中Re3+离子与MMA中C O存在配位作用,经本体聚合获得的有机玻璃呈非晶态,其溶解性好、透明性高,在各自最佳波长激发下能发射很强的Eu3+(613 nm)、Tb3+(544 nm)或Sm3+(644 nm)稀土特征荧光,其发光强度与Re(TTA)3/PMMA相当。更多还原

【Abstract】 Complexes Eu(OPrⁱ)（TTA）₂,Tb(OPrⁱ)（TTA）₂ and Sm (OPrⁱ)（TTA）₂ were synthesized by（replacing） partial isopropoxyl group with thenoyltrifluoroacetone（TTA） under the protection of N₂.The photoluminescent organic glass materials containing these complexes were prepared via the bulk polymerization of methyl methacrylate（MMA）/complex blends.The polymers containing these complexes were characterized by means of elemental analysis,FT-IR,XRD and FS.There existed interaction between the rare earth ions and the carboxyl group of MMA monomer.The organic glass materials containing Eu(OPrⁱ)-（TTA）₂,Tb(OPrⁱ)（TTA）₂ or Sm(OPrⁱ)（TTA）₂ exhibited strong characteristic luminescence of Eu³⁺（613 nm）,Tb³⁺（（544 nm）） or Sm³⁺（644 nm） under excitation at the most suitable wavelength for each compound,（respectively）.Their luminescent intensities were as high as that of PMMA containing Re（TTA）₃.In addition,the organic glass materials were amorphous and exhibited high solubility and transparence.更多还原
