Abstract

One‐for‐all phototheranostics, referring to a single component simultaneously exhibiting multiple optical imaging and therapeutic modalities, has attracted significant attention due to its excellent performance in cancer treatment. Benefitting from the superiority in balancing the diverse competing energy dissipation pathways, aggregation‐induced emission luminogens (AIEgens) are proven to be ideal templates for constructing one‐for‐all multimodal phototheranostic agents. However, to this knowledge, the all‐round AIEgens that can be triggered by a second near‐infrared (NIR‐II, 1000–1700 nm) light have not been reported. Given the deep tissue penetration and high maximum permissible exposure of the NIR‐II excitation light, herein, this work reports for the first time an NIR‐II laser excitable AIE small molecule (named BETT‐2) with multimodal phototheranostic features by taking full use of the advantage of AIEgens in single molecule‐facilitated versatility as well as synchronously maximizing the molecular donor‐acceptor strength and conformational distortion. As formulated into nanoparticles (NPs), the high performance of BETT‐2 NPs in NIR‐II light‐driven fluorescence‐photoacoustic‐photothermal trimodal imaging‐guided photodynamic‐photothermal synergistic therapy of orthotopic mouse breast tumors is fully demonstrated by the systematic in vitro and in vivo evaluations. This work offers valuable insights for developing NIR‐II laser activatable one‐for‐all phototheranostic systems.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
