Abstract

A triazatruxene-based initiator (TAT-SH) was synthesized and evaluated within the framework of thiol-ene click polymerizations from a green chemistry perspective. The findings indicate that the TAT-SH functions effectively even at low loadings. Notably, all reactions were completed within 1 min in the presence of only 1.0 mol% initiator, demonstrating a remarkable level of efficiency. The fact that the entire process proceeds under solvent-free conditions eliminates solvent-derived waste, thereby offering a clear environmental advantage. In addition, the chemical and thermal stability of TAT-SH supports both the reliable progression of reactions and the long-term usability of the initiator. Taken together, these features show that TAT-SH, through its rapid initiation capacity, high efficiency at low dosages, and compatibility with sustainable processing conditions, represents an innovative alternative compared to conventional initiators.

以三氮祖烷为基础的引发剂促进持续、超快、无溶剂的硫醇烯反应

合成了一种基于三氮扎鲁烷的引发剂（TAT-SH），并从绿色化学的角度对其进行了评价。研究结果表明，即使在低负荷下，TAT-SH也能有效地发挥作用。值得注意的是，在1.0 mol%引发剂存在的情况下，所有反应都在1分钟内完成，显示出显着的效率。事实上，整个过程在无溶剂条件下进行，消除了溶剂衍生的废物，从而提供了一个明显的环境优势。此外，TAT-SH的化学和热稳定性支持反应的可靠进展和引发剂的长期可用性。综上所述，这些特征表明，与传统引发剂相比，TAT-SH具有快速引发能力、低剂量下的高效率以及与可持续处理条件的兼容性，是一种创新的替代方案。

期刊介绍： European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas: Polymer synthesis and functionalization • Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers. Stimuli-responsive polymers • Including shape memory and self-healing polymers. Supramolecular polymers and self-assembly • Molecular recognition and higher order polymer structures. Renewable and sustainable polymers • Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites. Polymers at interfaces and surfaces • Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications. Biomedical applications and nanomedicine • Polymers for regenerative medicine, drug delivery molecular release and gene therapy The scope of European Polymer Journal no longer includes Polymer Physics.
