Aggregation‐Induced Energy Transfer Within a Donor–Acceptor–Donor Compound Featuring Hydrophobic Mesogenic Self‐Assembling Units
In this study, we report the design and synthesis of a novel donor-acceptor-donor-type organic emitter incorporating hydrophobic starburst mesogenic units. We have demonstrated that, in aqueous environments, this compound undergoes aggregation that induces efficient energy transfer within the molecules, resulting in tunable shifts in emission color. Molecular dynamics simulations corroborate the proposed mechanism by revealing the intramolecular assembly behavior. These findings provide valuable insights for the rational design of functional nano-aggregates targeted for applications in sensing and photonic materials.
