Regulation of Excitonic Effect in Donor–Acceptor Carbon Nitride for H2O2 Photosynthesis and Water Treatment
Constructing a donor–acceptor (D–A) structure in polymeric carbon nitride (PCN) extends the π‐conjugation for enhanced H2O2 photosynthesis, yet its impact on the excitonic effect remains underexplored. Herein, the exciton behavior and charge dynamics in D–A pairs were systematically regulated via rational donor design....
