Studies of the intermolecular interactions in polypyrrole and conjugated composites based on polypyrrole

Autopolymerization of Pyrrole in the Presence of a Host/Guest Calixarene

“…The above spectral features are similar to, but not identical with, those seen in spectra of highly doped polypyrrole. The latter typically exhibit two bands assigned to electronic transitions associated with bipolaron energy levels, at around 475 and 1240 nm, as well as a π−π* transition at shorter wavelengths. , Of the two bipolaron bands, the one at longer wavelengths is much broader and often the more intense. Figure contains a broad absorption band centered around 1000 nm that is consistent with assignment to a bipolaron band.…”
