The ability to combine two polymerization mechanisms in a one-pot setup and switch the monomer selectivity via an external stimulus provides an excellent opportunity to control polymer sequence and structure. We report a strategy that enables monomer incorporation to be determined via the selection of the wavelength of light through selective activation of either cationic or radical processes. This method enables the synthesis of varying polymeric structures under identical solution conditions but with simple modulation of the external stimulus. Additionally, changes in the ratios of the two photocatalysts afford complementary chemical control over these reactions to design elaborated polymeric structures. Our strategy takes advantage of the unique regulation that can be accessed through light.

阳离子和自由基聚合的光控互变

在一锅设置中结合两种聚合机制并通过外部刺激切换单体选择性的能力为控制聚合物序列和结构提供了极好的机会。我们报告了一种策略，该策略能够通过选择性激活阳离子或自由基过程来选择光的波长来确定单体的掺入。这种方法能够在相同的溶液条件下合成不同的聚合物结构，但对外部刺激进行简单调制。此外，两种光催化剂比例的变化提供了对这些反应的互补化学控制，以设计复杂的聚合物结构。我们的策略利用了可以通过光访问的独特监管。
