Carbazolic Conjugated Organic Polymers for Visible‐Light‐Driven CO 2 Photoreduction with H 2 O to CO with High Efficiency and Selectivity
Visible‐light‐driven CO 2 photoreduction with H 2 O to value‐added chemicals in high efficiency and selectivity is significant but challenging. Herein, a series of carbazolic conjugated organic polymers (CB‐COPs) with electron donor–acceptor (D–A) structures were prepared, which showed high efficien...
