Metal-free donor-acceptor photocatalysts enable efficient O-ATRP under visible light, allowing for precise control over polymer molecular weight with low dispersity. These photocatalysts achieve sufficient reductive potential to drive the reaction in their charge-transfer (CT) excited state. The reported efficient photocatalytic O-ATRP has significant potential in scalable polymer synthesis and photolithography.
无金属供体-受体光催化剂能够在可见光下实现高效的氧原子转移自由基聚合（O-ATRP），从而能够以低分散度精确控制聚合物分子量。这些光催化剂在其电荷转移（CT）激发态下具有足够的还原电位来驱动反应。所报道的高效光催化O-ATRP在可扩展的聚合物合成和光刻技术中具有巨大潜力。
