嵌段共聚物的应用多种多样,从电子学到功能化树脂再到治疗学。开环复分解聚合(ROMP)对于嵌段共聚物组装来说是一种特别有价值的反应,因为每个嵌段都可以通过长度控制来生成。我们试图通过实施一种策略,利用这种聚合来扩展嵌段共聚物的功能,该策略涉及对带有选择性反应基团的主链进行聚合后修饰。为此,我们证明ROMP可用于合成具有三种类型官能团的嵌段共聚物支架——琥珀酰亚胺酯、α-氯乙酰胺基团和酮——每种官能团都可以独立修饰。因此,可以精心设计单个支架以提供多种嵌段共聚物。利用这种合成方法和 ROMP 提供的长度控制,我们组装了能够穿过膜并进入哺乳动物细胞的嵌段共聚物。
The applications of block copolymers are myriad, ranging from electronics to functionalized resins to therapeutics. The ring-opening metathesis polymerization (ROMP) is an especially valuable reaction for block copolymer assembly because each block can be generated with length control. We sought to use this polymerization to expand the repertoire of block copolymers by implementing a strategy that involves post-polymerization modification of a backbone bearing selectively reactive groups. To this end, we demonstrate that ROMP can be used to synthesize a block copolymer scaffold that possesses three types of functional groups – a succinimidyl ester, an α-chloroacetamide group, and a ketone – each of which can be modified independently. Thus, a single scaffold can be elaborated to afford a wide range of block copolymers. Exploiting this synthetic approach and the length control offered by ROMP, we assemble block copolymers capable of traversing the membrane and entering mammalian cells.
