Abstract

Three-arm star azopyridinium salts self-organize into various morphologies in water/organic mixed solvents. Interesting AIE and self-assembling features are observed due to the strong interaction of the azopyridinium moieties with the highly polar H₂ O molecules causing the salts to aggregate, which restricts the molecular motion and induces the fluorescence.

Keywords: aggregation-induced emission; azopyridinium salts; ionic bonds; self-assembly; supramolecular chemistry.
