  Macromolecular organic photocatalysts consisting of a completely conjugated network have broad and promising applications in visible light-promoted photoredox catalysis. Precise reproduction and control of exact conjugation length remains an important challenge for fully conjugated and macromolecular photocatalysts. Here, we introduce a new photocatalytic material based on classical PMMA copolymerised

  由完全共轭网络组成的高分子有机光催化剂在可见光促进的光氧化还原催化中具有广泛而有希望的应用。对于完全共轭的高分子光催化剂，精确的复制和精确的共轭长度控制仍然是一个重要的挑战。在这里，我们介绍一种基于经典PMMA的新型光催化材料，其与定义的电子供体和受体单元共聚合，具有精确可控的氧化还原电势和共轭长度，从而创造了一种有希望的无金属，稳定且低成本的多相光催化剂。此外，PMMA共聚物基质在有机溶剂中的溶胀导致底物扩散增强，从而提高了催化效率。在空气中以低有效光催化剂负载量实现光催化[4 + 2]环加成反应的高效率和选择性。PMMA光催化剂的光催化效率与最新的金属或非金属催化剂相当，同时具有易于回收利用的特点。
