Visible light-induced polymerization, as a promising and green strategy, is showing great potential in preparing value-added polymers. Herein, a visible light photoredox catalysis method is reported to afford a library of polyamide with high yields (up to 99%) and high molecular weights (Ms) (up to 71 000 g mol). Dithioacids and diamines as the monomers, and 9-mesityl-10-methylacridinium tetrafluoroborate (Mes-Acr-MeBF) as the organic photoredox catalyst give the polyamides with structural diversity in air under mild conditions without extra metal, base, or additives.
可见光诱导聚合作为一种有前景的绿色策略，在制备高附加值聚合物方面显示出巨大潜力。在此，报道了一种可见光光氧化还原催化方法，可提供一系列高产率（高达99%）和高分子量（高达71000 g/mol）的聚酰胺。以二硫代酸和二胺为单体，9-均三甲苯基-10-甲基吖啶四氟硼酸盐（Mes-Acr-MeBF）为有机光氧化还原催化剂，在温和条件下于空气中无需额外的金属、碱或添加剂即可得到结构多样的聚酰胺。
