Fluorescence visualization of the molecular assembly processes during solvent evaporation via aggregation-induced emission in a cyanostilbene derivative

Abstract

The initial stage of organic crystal formation during solvent evaporation was observed using aggregation-induced enhanced emission, indicating that the fluorescence from the J-aggregates was established prior to the increase in total intensity at the assembly process. This suggests that the kinetics of the transformation of J-aggregates into embryonic nuclei, and subsequently into crystals, can be visualized using fluorescence.
