Abstract Aiming to achieve versatile phototheranostics with the integrated functionalities of multiple diagnostic imaging and synergistic therapy, optimum use dissipated energy through both radiative nonradiative pathways is definitely appealing, yet a significantly challenging task. To best knowledge, there have been no previous reports on single molecular species effective at affording all phototheranostic modalities including fluorescence (FLI), photoacoustic (PAI), photothermal (PTI), photodynamic therapy (PDT), (PTT). Herein, simple highly powerful one‐for‐all based aggregation‐induced emission (AIE)‐active fluorophores tactfully designed constructed. Thanks its strong electron donor–acceptor interaction finely modulated intramolecular motion, AIE fluorophore‐based nanoparticles simultaneously exhibit bright near‐infrared II (NIR‐II) emission, efficient reactive oxygen generation, high conversion efficiency upon NIR irradiation, indicating actualization balance between dissipations. Furthermore, unprecedented performance NIR‐II FLI‐PAI‐PTI trimodal‐imaging‐guided PDT–PTT demonstrated by precise tumor diagnosis complete elimination outcomes. This study thus brings new insight into development superior for practical cancer theranostics.
