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。
Based on the synthesis of polyurethane acrylate macromonomer, a series of highly transparent La (Phen) 2Cl3DMF (DMF) 2 / urethane acrylate rare earth polymers were prepared by in situ polymerization. The relevant properties of the material were characterized. The results show that the rare earth polymer has good transparency, thermal stability and photoluminescence. When the content of La (Phen) 2Cl3DMF (DMF) 2 is 1%, the transmittance of the material reaches 91.8 %. Under the excitation wavelength of 320nm, the maximum fluorescence emission peak appears at 367nm, which is expected to be used in the field of functional optical materials.
