摘要

在使用或不使用光催化剂的情况下，使用碳酸三硫酯基链转移剂（CTA）和丙烯酸酯基单体进行了光介导可逆加成碎片链转移（RAFT）阶跃生长聚合反应。通过顺序添加单体的单锅合成接枝共聚物，证明了光介导 RAFT 梯级生长的多功能性。此外，通过适当选择光催化剂和溶剂对（四苯基卟啉锌 [ZnTPP] 和二甲基亚砜 [DMSO]），还证明了光介导 RAFT 梯级生长的耐氧性，从而实现了露天条件下的超低体积聚合。

Photo-Mediated RAFT Step-Growth Polymerization With Diacrylate Monomers: Investigating Versatility and Oxygen Tolerance.

Photomediated reversible addition fragmentation chain transfer (RAFT) step-growth polymerization is performed using a trithiocarbonate-based chain transfer agent (CTA) and acrylate-based monomers both with and without a photocatalyst. The versatility of photo-mediated RAFT step-growth is demonstrated by one-pot synthesis of a graft copolymer via sequential monomer addition. Furthermore, oxygen-tolerant photo-mediated RAFT step-growth is demonstrated, facilitated by the appropriate selection of photocatalyst and solvent pair (zinc tetraphenyl porphyrin [ZnTPP] and dimethyl sulfoxide [DMSO]), enabling ultralow volume polymerization under open-air conditions.
