Abstract

Functional dyes with absorption in the second near-infrared window (NIR-II) show great promise in photothermal therapy. Herein, the novel NIR-II 3,5-julolidinyl aza-BODIPY ( JLD ) was prepared and confirmed by X-ray crystallographic analysis for the first time. The molecular packing structure facilitates the J -aggregation packing mode. Self-assembled JLD -nanoparticles ( JLD -NPs) emit fluorescence (λ em = 962 nm, Φ f = 0.1%), and a peak belt covered a NIR-II range of 900–1300 nm. The photothermal conversion efficiency was high and was calculated to be 79%. JLD -NPs with NIR-II 915 nm laser irradiation had the good tumor-inhibition capability with promoting the apoptosis and inhibiting the stemness of glioblastoma cells by brain stereotactic injection and affect the occurrence of malignant events, such as migration and invasion.

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.
