摘要

无金属供体-受体光催化剂可在可见光下实现高效的 O-ATRP 反应，从而以较低的分散性精确控制聚合物的分子量。这些光催化剂具有足够的还原电势，可在电荷转移（CT）激发态下驱动反应。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方面具有巨大潜力。

Metal-free photocatalysts with charge-transfer excited states enable visible light-driven atom transfer radical polymerization.

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.
