An AIEgen‐Based Covalent Organic Polymer With NIR‐II Emission for 980 nm Excitable Tumor Phototheranostics
Covalent organic porous polymers (COPs) represent an attractive platform for phototheranostics due to their structural tunability and extended conjugation. Nevertheless, achieving COPs that simultaneously exhibit efficient second near‐infrared (NIR‐II) fluorescence and long‐wavelength excitation remains a considerabl...
