Abstract

Thiol-functionalized polymers have become a crucial class of materials due to their distinct chemical properties and versatile reactivity, leading to a broad spectrum of applications. Herein, we report the straightforward syntheses of a wide range of thiol-end-functionalized ring-opening metathesis polymerization (ROMP) polymers exploiting our previously reported catalytic ROMP mechanisms using suitable chain transfer agents. All the synthesized polymers were characterized via SEC, ¹H NMR spectroscopy and MALDI-ToF mass spectrometry techniques. Furthermore, the existence of thiol groups on the polymer chains was verified through the well-established thiol coating reaction on gold nanoparticle surfaces. We believe this method of synthesizing thiol-end-functionalized ROMP polymers (using a reduced amount of ruthenium metal compared to conventional living ROMP) will be of great importance to materials science and biochemical research.

硫醇端官能化 ROMP 聚合物的催化合成

硫醇官能化聚合物因其独特的化学性质和多变的反应活性而成为一类重要的材料，应用领域十分广泛。在此，我们报告了利用之前报道的催化开环偏聚（ROMP）机理，使用合适的链转移剂直接合成了多种硫醇端官能化开环偏聚（ROMP）聚合物。所有合成聚合物都通过 SEC、1H NMR 光谱和 MALDI-ToF 质谱技术进行了表征。此外，聚合物链上硫醇基团的存在还通过金纳米粒子表面成熟的硫醇涂层反应得到了验证。我们相信，这种合成硫醇端官能化 ROMP 聚合物的方法（与传统的活体 ROMP 相比，使用的钌金属量更少）将对材料科学和生物化学研究具有重要意义。

期刊介绍： ACS Macro Letters publishes research in all areas of contemporary soft matter science in which macromolecules play a key role, including nanotechnology, self-assembly, supramolecular chemistry, biomaterials, energy generation and storage, and renewable/sustainable materials. Submissions to ACS Macro Letters should justify clearly the rapid disclosure of the key elements of the study. The scope of the journal includes high-impact research of broad interest in all areas of polymer science and engineering, including cross-disciplinary research that interfaces with polymer science. With the launch of ACS Macro Letters, all Communications that were formerly published in Macromolecules and Biomacromolecules will be published as Letters in ACS Macro Letters.
