摘要:

近红外二区(NIR-II, 1000~1700 nm)染料因具有更强的组织穿透能力、 更低的光散射以及更弱的组织自发荧光干扰, 已成为活体荧光成像领域的研究热点. 在多种聚集态体系中, J-聚集体通常由染料分子以“头尾相接”或“滑移堆积”的方式有序排列, 导致吸收与发射光谱发生显著红移, 为获得NIR-II发射提供了有效策略. 近年来, 研究者报道了多种氟硼二吡咯亚甲基(BODIPY)衍生物, 可通过分子设计与自组装构筑具有优良光物理性质的NIR-II区J-聚集体, 其核心构筑策略在于通过引入空间位阻、 调控电子效应或构建非共价相互作用网络, 有效阻断骨架间的H-面对面堆积, 进而诱导并稳定高度有序的J-型滑移堆积. 本文综合评述了基于BODIPY的NIR-II J-聚集体在分子设计与合成、 自组装行为与结构调控方面的研究进展, 并总结了其在生物成像、 光热治疗(PTT)、 光动力治疗(PDT)及光诊疗一体化等生物医学应用中的最新进展. 此外, 讨论了该类BODIPY染料目前面临的各种挑战及未来发展机遇.

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.
