A benzothiadiazole‐based covalent organic framework (COF) with efficient two‐photon induction performance was synthesized as described by X.‐Z. Zhang and co‐workers in their Research Article on page 10087. The unique structure of the COF attenuates π–π stacking interactions between the layers, and overcomes aggregation‐caused emission quenching of chromophores for improved near‐infrared two‐photon‐induced fluorescence imaging.
