polymerization. The terpyridine-terminated macromolecules with well-defined structures were further used for preparation of supramolecular diblock metallomacromolecules by bis(2,2‘:6‘,2‘ ‘-terpyridine)ruthenium(II) complex connectivity. The successful connectivity between two macromolecular blocks via the metallocomplex was confirmed by UV−vis, size exclusion chromatography (SEC), and differential scanning
我们报告了合成和使用的新型三联吡啶官能化链转移剂(CTA),可逆的加成-断裂链转移(RAFT)聚合产生在一个链端具有三联吡啶官能度的良好控制的大分子结构。具有明确结构的三联吡啶末端的大分子还被用于通过双(2,2':6',2''-三联吡啶)钌(II)络合物连接制备超分子二嵌段金属大分子。UV-vis,尺寸排阻色谱法(SEC)和差示扫描量热法(DSC)以及原子力显微镜(AFM)技术证实了通过金属配合物在两个大分子嵌段之间的成功连接。
