Cavity-Size-Directed Supramolecular Assembly of AIEgen Networks for Aqueous White-Light Emission

Abstract

We demonstrate a cucurbit[n]urils (CB[n])-based strategy to direct the emission of AIEgens. While CB[7] enhances fluorescence via molecular motion restriction, the larger CB[8] induces a blue shift and enables co-encapsulation for an efficient FRET system with an anthracene guest, achieving white-light emission in water. This work establishes host size and guest alignment as key determinants for designing aqueous AIEgen materials.
