The development of multi-component orthogonal polymerizations (MOPs) with simple procedure and high efficiency is crucial for rational polymer synthesis. In this work, photo-triggered Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) polymerization are first investigated, employing copper(II) thioxanthone carboxylate (Cu(TX) ) as photoredox catalyst and sunlight as stimuli. Then, the novel MOPs using one photoredox catalyst, Cu(TX) to simultaneously mediate two different photopolymerizations, are successfully realized in one-pot, where photo-induced electron transfer atom transfer radical polymerization and photo-activated CuAAC polymerization can effectively proceed in a one-pot and non-interfering fashion to afford predetermined copolymers with well-defined structure.
开发具有简单流程和高效率的多组分正交聚合反应（MOPs）对于合理的聚合物合成至关重要。在这项工作中，首先研究了光引发的铜（I）催化叠氮化物-炔烃环加成（CuAAC）聚合反应，使用硫代呫吨酮羧酸铜（II）（Cu(TX)）作为光氧化还原催化剂，并以阳光作为刺激源。然后，成功实现了使用一种光氧化还原催化剂Cu(TX)同时介导两种不同光聚合反应的新型MOPs，在一锅反应中，光诱导电子转移原子转移自由基聚合反应和光活化CuAAC聚合反应能够以一锅法且互不干扰的方式有效进行，从而得到具有明确结构的预定共聚物。
