D–A–π–A–D Type Photosensitive Covalent Organic Framework for Efficient Photocatalytic Aerobic Oxidation

D–A–π–A–D Type Photosensitive Covalent Organic Framework for Efficient Photocatalytic Aerobic Oxidation

Oxidation reactions are a fundamental type of reaction in chemical synthesis and material preparation. The visible light-driven photocatalytic aerobic oxidation, which directly and efficiently converts solar energy into chemical energy through photocatalysts under mild conditions, has become one of the most promising oxidation technologies due to its sustainability advantages. Therefore, photocatalytic aerobic oxidation is widely … Read more

Potent Covalent Organic Framework Nanophotosensitizers for Photodynamic Immunotherapy

iNature The photodynamic therapy (PDT) using oxygen-dependent type II photosensitizers is often limited by the hypoxic microenvironment of solid tumors. Type I photosensitizers generate oxygen-independent reactive oxygen species (ROS) under light irradiation, but they suffer from aggregation-caused quenching (ACQ) and low ROS generation efficiency. On December 19, 2024, the team led by Ge Zhishen from … Read more
