Supramolecular structure of J-aggregates of a sulfonate substituted amphiphilic carbocyanine dye in solution: Methanol-induced ribbon-t

Article Abstract:

Replacing the pH-sensitive carboxyl substituents of amphiphilic 5,5',6,6'-tetrachlorobenzimidacarbocyanine dyes by sulfonyl substituents promotes the formation of novel types of J-aggregates in aqueous solution. Results of the effects of methanol are presented that were studied in detail.

Stabilization of individual tubular J-aggregates by poly(vinyl alcohol)

Article Abstract:

The influence of poly(vinyl alcohol) (PVA) on the morphology and spectroscopy of J-aggregates of the benzimidacarbocyanine dye C8O3 is investigated. It is observed that the C8O3 J-aggregates dispersed in PVA thin films reveal the same four-banded spectrum.
