The first versatile gas-controlled polymerization switch based on reversible absorption of CO₂ by organic amidine was developed. The amidine/alcohol system, which originally belonged to CO₂ binding organic liquids, served as an efficient CO₂-responsive catalyst/initiator system for lactide polymerization. Chemoselective block copolymerization between polylactide and polycarbonate was further explored by opposite gas-controlled amidine and another Cr^III catalyst, where an immortal strategy was developed for conjugated alternation of inverse polymerizations on different active species and permits many potential applications.

CO ₂受控催化：可切换均聚和共聚

研发了第一个基于有机am可逆吸收CO ₂的多功能气体控制聚合开关。最初属于结合CO _2的有机液体的am /醇体系，可作为丙交酯聚合反应的高效CO ₂响应型催化剂/引发剂体系。聚丙交酯和聚碳酸酯之间的化学选择性嵌段共聚反应是通过相反的气体控制am和另一种Cr ^III催化剂进行的，其中开发了一种永生策略，用于在不同的活性物种上进行逆向聚合反应的共轭交替，并具有许多潜在的应用前景。
