Аннотация: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 fi brils, redshifted
with respect to highly crystalline PANI fi lm 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 confi
rmed by atomistic molecular dynamics simulations.
