J-like supramolecular assemblies of polyaniline in water
Original language description
The consideration of polyaniline (PANI) as a supramolecular assembly similar to J-aggregates of dyes is proposed. Fibrils with a length of more than 100 nm and a diameter of about 4 nm are formed in water during aniline polymerization, as shown by small-angle X-ray scattering. Long-wavelength absorption of the fibrils, red-shifted with respect to highly crystalline PANI film supports the idea about the formation of J-aggregates. Their formation, similar to dyes, is promoted by the addition of a sulfonated polyelectrolyte and becomes more pronounced with an increase of the molar mass of the polyelectrolyte. Self-organization of aniline oligomers in a polar environment is confirmed by atomistic molecular dynamics simulations.
