主要研究了稀土铕离子配合物中两亲性嵌段共聚物和小分子配体对铕离子荧光性能的影响。通过可控/“活性”自由基聚合方法中的可逆加成-断裂转移(RAFT)法合成一系列具有不同链段长度的两亲性嵌段共聚物:聚甲基丙烯酸甲酯-b-聚丙烯酸(PMMA-b-PAA)。在适当的溶剂N,N-二甲基甲酰胺(DMF)中,以稀土铕离子作为诱导中心,邻菲罗啉(phen)作为小分子配体协同反应,诱导聚甲基丙烯酸甲酯-b-聚丙烯酸(PMMA-b-PAA)进行自组装。成功制备了尺寸可控并具有优良荧光性能的球形纳米胶束,调整球形胶束的尺寸可以应用于有机物太阳能电池等光伏领域。
The effects of amphiphilic block copolymers and small molecule ligands on the fluorescence of europium ions in rare earth europium ion complexes were studied. A series of amphiphilic block copolymers with different segment lengths were synthesized by reversible addition-fragmentation transfer (RAFT) method in a controlled / “living ” free radical polymerization process: polymethylmethacrylate-b Polyacrylic acid (PMMA-b-PAA). In the appropriate solvent N, N-dimethylformamide (DMF), rare earth europium ions as the induction center, phenanthroline (phen) as a small molecule ligand synergistic response to induce polymethyl methacrylate-b - Polyacrylic acid (PMMA-b-PAA) for self-assembly. The spherical nano-micelles with controlled size and excellent fluorescence performance were successfully prepared. The size of the spherical micelles can be adjusted and applied to photovoltaic fields such as organic solar cells.
