The necessity of sustainable development in the chemical industry has continuously drawn attention to find safe, environmentally friendly and atom-economic chemical processes, which is defined in the 12 principles of green chemistry. Merging photoredox catalysis and reversible addition-fragmentation chain transfer (RAFT) polymerisation, the photoinduced electron/energy transfer (PET)-RAFT process has opened up a new way of performing reversible deactivation radical polymerisation for well-defined polymer synthesis using light as an external stimulus. While providing an increased level of control (spatiotemporal, wavelength, and intensity control) over the polymerisation, PET-RAFT has many attractive attributes (abundant catalyst availability, catalyst recyclability, selectivity and oxygen tolerance) to be green and sustainable, which is intriguing for precision polymer manufacturing in industry.
在化学工业中，可持续发展的必要性不断引起人们的关注，需要寻找安全、环保和原子经济的化学工艺，这一定义在绿色化学的 12 条原则中有体现。光氧化还原催化和可逆加成-断裂链转移（RAFT）聚合的结合，使光诱导电子/能量转移（PET）-RAFT 过程为使用光作为外部刺激进行可控的自由基聚合提供了一种新途径，从而实现了聚合物的合成。虽然 PET-RAFT 为聚合反应提供了更高水平的控制（时空、波长和强度控制），但它具有许多吸引人的属性（丰富的催化剂可用性、催化剂可回收性、选择性和耐氧性），是绿色和可持续的，这对于工业中的精密聚合物制造具有吸引力。
