Abstract
Conjugated polymers are indispensable materials in organic optoelectronics. Living chain-growth polymerization has emerged as a promising strategy for synthesizing conjugated polymers with narrow polydispersity indices. To date, the majority of living chain-growth polymerization protocols have relied on Kumada-type cross-coupling reactions using aryl halides as monomers. Herein, we developed a nickel-catalyzed living chain-growth polymerization method based on carbon–sulfur bond activation, employing aryl sulfides as monomers, which enabled the synthesis of poly(3-hexylthiophene) (P3HT) with a regioregularity exceeding 95%. Kinetic studies confirmed the chain-growth mechanism of the polymerization, while steric hindrance and electronic effects were found to play important roles in regulating the polymerization behavior.
期刊介绍：
Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985.
CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
