A novel near‐infrared (NIR)‐emissive amphiphilic BODIPY derivative, BBDP, was successfully prepared and thoroughly characterized. The photophysical properties in various organic solvents and THF/H 2 O mixtures with different fractions of water were investigated. BBDP self‐assembled into nanofibers in a water environment owing to its amphiphilic properties. Through charge‐transfer interactions, BBDP co‐assembled with a perylene bisimide derivative, PBI, and a viologen derivative, MV, to generate two superamphiphiles. These two superamphiphiles were able to aggregate in water media at appropriate concentrations. The BBDP–PBI charge‐transfer complex formed nanorods, whereas the BBDP–MV aggregates expressed a disk‐like morphology. This research paves the way for us to manipulate the morphology of dye assemblies.
