Abstract

Abstract: 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/H2 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. Abstract : Gather'round : The suprastructure of nanoaggregates can be regulated by introducing a charge‐transfer interaction. A boron–dipyrromethene (BODIPY) derivative, BBDP, can self‐assemble into nanofibers in water media. BBDP interacts through charge transfer with a perylene bisimide derivative, PBI, and a viologen derivative, MV, to form two novel charge‐transfer complexes. The BBDP–PBI nanoaggregates have a nanorod morphology, whereas the BBDP–MV complex self‐assembles into nanodisks.
