Post-modification of polymers offers a route to prepare functionalized polymers through efficient chemical reactions, and hydrosilylation is one of the most effective strategies. Silane-functionalized polymers have found a wide range of potential applications, such as adhesives, rubbers, and drug delivery agents. For decades, the hydrosilylation for the post-modification of polymers has typically used
聚合物的后改性提供了一种通过有效的化学反应制备功能化聚合物的途径,而氢化硅烷化是最有效的策略之一。硅烷官能化聚合物具有广泛的潜在应用,例如粘合剂、橡胶和药物输送剂。几十年来,聚合物后改性的氢化硅烷化通常使用过渡金属作为催化剂。该领域很大程度上缺乏能够避免聚合物中金属残留的无金属氢化硅烷化策略。在此,我们报道了在蓝光照射下使用有机光催化剂和氢原子转移(HAT)催化剂对带有乙烯基侧基的聚合物进行后改性的光催化金属自由基氢化硅烷化策略。
