of side chain grafting on the luminescent properties of polymer solutions, including quantum yields. It was shown that an optimal length of polymethacrylicacid side chains provides solubility of the polymer brushes. Solutions of PF-graft-polymethacrylic acid complexes with the model substance curcumin were investigated. It was established that the molecular brushes containing curcumin form monomolecular
通过原子转移自由基聚合制备了一系列具有聚芴(PF)主链和不同长度的聚甲基丙烯酸侧链的分子刷。合成的化合物的结构和组成均通过1 H NMR和IR光谱证实。分析了主链长度对溶液中大分子光谱和构象参数的影响。侧链接枝密度约为90%。光谱方法已用于确定侧链接枝对聚合物溶液发光性能(包括量子产率)的依赖性。结果表明,聚甲基丙烯酸侧链的最佳长度提供了聚合物刷的溶解度。研究了PF-接枝-聚甲基丙烯酸络合物与模型物质姜黄素的溶液。已确定含有姜黄素的分子刷形成单分子胶束。研究了含有锌酞菁的分子刷、光动力和光热疗法的潜在系统。
