Control of electron–lattice interaction in organic nanoclusters

In this study we demonstrate that the electron–lattice interaction (ELI) could be controlled by changing exciton delocalization length in ordered organic nanoclusters called J-aggregates. Particularly it could be done via the J-aggregates solvate shell manipulation using surfactants. The strong correlation between the J-aggregates luminescence quantum yield and the ELI strength has been reviled that allows us to consider the exciton self-trapping as the main mechanism of the J-aggregates luminescence losses.

► The way of electron–lattice interaction control has been shown. ► It has been done via solvate shell around J-aggregates manipulation. ► ELI strength defines exciton self-trapping probability in J-aggregates. ► The exciton self-trapping is the main mechanism of J-aggregates luminescence losses.
