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/H2O 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.
