离子凝胶是一种将离子液体固定在Si-O基质凝胶材料中的新型离子液体固态材料。首先通过溶胶-凝胶法合成均匀透明的离子凝胶材料,然后利用离子液体这一良好溶剂及其在凝胶材料中的可循环性,通过提取离子液体及再吸附稀土铽配合物与离子液体的溶液,实现铽配合物在离子凝胶材料中均匀稳定的掺杂。合成了两种铽β-二酮配合物复合离子凝胶材料并研究材料光致发光性能,发现复合材料中铽配合物保持了Tb(Ⅲ)的特征发射,其荧光寿命在复合材料中略变短,该复合材料方法简单,合成条件温和且环保,材料的合成为稀土配合物的应用提供了又一类新型复合材料。
Iongel is a new type of ionic liquid solid material that fixes ionic liquids in Si-O matrix gel materials. Firstly, a uniform and transparent iongel material was synthesized by sol-gel method. Then, using the good solvent of ionic liquid and its recyclability in gel material, the ionic liquid and the reabsorption of rare earth terbium complex and ionic liquid Of the solution to achieve uniform and stable doping of the terbium complex in the ion gel material. The terbium-β-diketone complex iongel materials were synthesized and their photoluminescence properties were studied. It was found that the terbium complexes in the composites retained the characteristic emission of Tb (Ⅲ), and their fluorescence lifetime slightly shortened in the composites , The composite method is simple, the synthesis conditions are mild and environment-friendly, and the synthesis of the materials provides a new type of composite material for the application of rare earth complexes.
