Abstract:

Near-infrared II(NIR-II, 1000—1700 nm) dyes have emerged as a promising tool for in vivo fluorescence imaging due to their enhanced tissue penetration, reduced light scattering, and minimized autofluorescence interference. In various aggregated systems, J-aggregates typically form through “head-to-tail” or “slip-stack” arrangements of dye molecules, resulting in a pronounced red shift in both absorption and emission spectra, offering an effective strategy for achieving NIR-II emission. Recent studies have introduced a range of borondipyrromethene(BODIPY) derivatives that, through molecular design and self-assembly, form NIR-II J-aggregates with excellent photophysical properties. The core construction strategy lies in effectively blocking H-face-to-face stacking between the backbone by introducing steric hindrance, regulating electronic effects, or constructing non-covalent interaction networks, thereby inducing and stabilizing highly ordered J-type slip stacking. This review provides a comprehensive overview of the progress in the molecular design, synthesis, self-assembly behavior, and structural regulation of BODIPY-based NIR-II J-aggregates. Furthermore, it highlights their recent advancements in biomedical applications, including biological imaging, photothermal therapy(PTT), photodynamic therapy(PDT), and integrated theranostics. The challenges and future perspectives for BODIPY-based NIR-II dyes are also discussed.
