Manipulating Charge Distribution of Graphitic Carbon Nitride for Boosting NIR-II Light-Activated Reactive Oxygen Species Generation.
Structure engineering is of great importance to enhance the carrier separation efficiency of multiphoton absorption (MPA) materials for near-infrared (NIR) light-driven reactive oxygen species (ROS) generation. In this study, the MPA-responsive potassium/cyano group-functionalized graphitic carbon nitride was investigated, demonstrating charge redistribution and improved carrier separation efficiency by density functional theory calculations and experimental results. With various types of boosted ROS generation under UV-vis or NIR-II light irradiation, the potassium/cyano group-functionalized graphitic carbon nitride could achieve efficient multiphoton photodynamic therapy after reducing the particle size. This study developed a simple strategy to manipulate charge distribution for booting NIR light-activated ROS generation in efficient multiphoton photodynamic therapy.
