Fluorescent supramolecular cages have attracted significant scientific interest owing to their widespread applications in molecular sensing, luminescent materials, and biological systems. However, the modular construction of such assemblies with tunable emission behaviors affording high-performance bioimaging is still challenging. Herein, we developed a general straightforward protocol formulate an aggregation-induced (AIE) tendency by using "donor–acceptor–donor (D–A–D)" adducts as building blocks. A series box-shaped MA–MG adjustable fluorescence from red second near-infrared (NIR-II) region were successfully prepared. In particular, maximum MG was located at 981 nm, behaving like rare NIR-II emissive thus far, cage-loaded nanoparticles MGNPs featured high absolute quantum yield region, which enabled them perform well blood vessel imaging.
