Abstract

Solution state protonation (doping) studies have been made using
polyemeraldine and the phenyl capped tetramer oligomer of emeraldine.
The spectra show in detail the changes which occur in the electronic
structure of these materials upon doping and indicate that imine sites
can be protonated singularly and that homogeneous protonation occurs at
all protonation levels. Ageing in solution and dilution experiments
indicate that solvation effects, probably rigid rod to coil, occur on a
relatively long time scale.
