近些年来,由于稀土离子的独特的光学性能而使稀土有机化合物(包括高分子)的合成、结构及性能研究广泛地开展起来。现在,人们已经成功地把含稀土的高分子探针应用于研究含金属的高分子和生物高分子的结构及构象研究,人们还在积极地研制稀土类功能材料,并且已经取得了一定的进展。然而,尽管人们在稀土有机化合物的合成和研究上取得了很大的成功,但仍存在着以下的不足。首先,就研究光学性能的含稀土的高分子来看,现在仍存在着品种较为单一的现象。一般人们所用的高分子材料无非就是在高分子的侧链或端基上引入羧基,从而能和稀土离子作用以把稀土离子引
In recent years, due to the unique optical properties of rare earth ions, the synthesis, structure and properties of rare earth organic compounds (including polymers) have been extensively studied. Now, people have successfully applied rare earth-containing polymer probes to study the structure and conformation of metal-containing polymers and biopolymers, and they are still actively developing rare earth functional materials and have made some progress . However, despite the great success achieved in the synthesis and research of rare earth organic compounds, the following deficiencies still exist. First of all, to study the optical properties of rare earth-containing polymers point of view, there is still a more single species phenomenon. Most people use the polymer material is nothing more than the introduction of carboxyl groups in the polymer side chain or terminal, which can interact with rare earth ions to lead rare earth ions
