Two-dimensional (2D) materials have great potential in macromolecular synthesis, yet there are some areas that still need to be explored, such as anionic polymerization. In this study, we present the first example of photoinduced anionic polymerization of ethyl-2-cyanoacrylate (ECA) using 2D graphitic carbon nitride (g-C₃N₄) as an active photocatalyst responsive to visible light. Our results demonstrate that particularly the mesoporous structure of g-C₃N₄ can initiate polymerization through the generation of electron–hole pairs upon exposure to visible light. To have a better insight into mechanistic pathways, several experiments, including control experiments, are conducted. The obtained polymers and the synthesized g-C₃N₄ materials are characterized comprehensively by chromatographic, thermal, and spectroscopic techniques. Accordingly, this study demonstrates an innovative process that can offer several advantages over traditional polymerization methods, including the ability to initiate polymerization at ambient temperatures and achieve high polymerization rates.

2-氰基丙烯酸乙酯与石墨碳氮化物的可见光诱导阴离子光聚合

二维（2D）材料在高分子合成方面具有巨大潜力，但仍有一些领域需要探索，例如阴离子聚合。在这项研究中，我们提出了使用二维石墨氮化碳（gC ₃ N ₄）作为对可见光敏感的活性光催化剂进行2-氰基丙烯酸乙酯（ECA）光诱导阴离子聚合的第一个例子。我们的结果表明，gC ₃ N ₄的介孔结构在暴露于可见光时可以通过产生电子空穴对来引发聚合。为了更好地了解机制途径，进行了一些实验，包括对照实验。通过色谱、热学和光谱技术对所得聚合物和合成的gC ₃ N ₄材料进行了综合表征。因此，本研究展示了一种创新工艺，与传统聚合方法相比，该工艺具有多种优势，包括能够在环境温度下引发聚合并实现高聚合速率。
