fast polymer postfunctionalization and step-growth polymerization (via addition reaction) under aerobic condition was developed from visible light photocatalytic thiol–ene “click” reaction, employing Ru(bpy)3Cl2 as photoredox catalyst and p-toluidine as redox mediator. The nature of the photoredox catalysts, thiol substrates, and solvents were extensively investigated for this reaction with two types
利用Ru(bpy)3 Cl 2作为光氧化还原催化剂和对甲苯胺作为可见光,利用可见光光催化硫醇-烯“点击”反应开发了一种好氧条件下快速聚合物后官能化和逐步增长聚合(通过加成反应)的巧妙方法。氧化还原介体。对于与两种类型的烯烃聚合物:聚丁二烯和聚(甲基丙烯酸烯丙酯)的反应,光致氧化还原催化剂,硫醇底物和溶剂的性质已得到广泛研究。使用ñ -甲基-2-吡咯烷酮作为溶剂,p-甲苯胺作为氧化还原介体显着提高了反应速率并限制了副产物的形成。最后,这种高效的硫醇-烯反应被用于通过逐步增长加成聚合反应合成聚合物。
