中文摘要：

在合成聚氨酯丙烯酸酯大分子单体的基础上，利用原位聚合法制备出一类高透明性的稀土配合物La（Phen）2Cl3DMF·（DMF）2／聚氨酯丙烯酸酯稀土高分子材料，并对材料的相关性能进行了表征。结果表明，该类稀土高分子材料具有良好的透明性、热稳定性和光致发光性；当配合物La（Phen）2Cl3DMF·（DMF）2的含量为1％时，材料的透光率达91．8％；且在波长为320nm的激发光下，材料在367nm出现最大荧光发射峰，有望应用在功能光学材料领域。

英文摘要：

The transparent rare earth polymers of La（Phen）2 Cl3DMF·（DMF）2/poylurethane acrylate were prepared by in-situ polymerization based on macromonomers of polyurethane acrylate, and the properties of the materials were characterized. The results show that the materials have excellent transparency, heat stability and photoluminescence. While the mass ratio of the rare earth complex is 1%, the spectral transmittance of this polymer is 91.8%, and the strongest fluorescence emission peak of the rare earth polymer appears at 367nm when the excitation wavelength is 320nm. This material can be applied for the fields of functional optical material.
