摘要

在此，我们报告了分别作为光催化剂和链转移剂的二氧化钛纳米颗粒和三硫代碳酸酯衍生物促进紫外线诱导的受控自由基聚合。聚合是通过可逆的加成-断裂链转移（RAFT）过程进行的。所得到的聚合物分子量控制得很好，多分散性相对较低。此外，通过使用二氧化钛纳米粒子进行紫外线诱导的 RAFT 聚合反应，链延伸反应产生了更高分子量的聚合物产品。

UV-induced Controlled Radical Polymerization Using Titanium Dioxide Nanoparticles Via the RAFT Process

Herein, we report the UV-induced controlled radical polymerization facilitated by titanium dioxide nanoparticles and trithiocarbonate derivatives, serving as photocatalysts and chain transfer agents, respectively. The polymerization proceeded through a reversible addition–fragmentation chain transfer (RAFT) process. The resulting polymers exhibited well-controlled molecular weights and relatively low polydispersity. Additionally, the chain extension reaction via UV-induced RAFT polymerization using titanium dioxide nanoparticles yielded higher-molecular weight polymer products.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
