Strategic construction of fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents for amplifying cancer phototheranostics

FlexMat, EarlyView.
The development of conventional phototheranostic nanomedicines suffers from an intrinsic trade‐off between NIR‐II fluorescence emission and phototherapeutic effects, leading to poor overall efficacy. Herein, we propose an innovative fluorination strategy by constructing fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents to ...
