SOLUTION-STATE DOPING STUDIES OF THE POLYEMERALDINE CAMPHOR SULFONIC-ACID SYSTEM

Solution state protonation (doping) studies have been made using polye meraldine and the phenyl capped tetramer oligomer of emeraldine. The s pectra show in detail the changes which occur in the electronic struct ure of these materials upon doping and indicate that imine sites can b e protonated singularly and that homogeneous protonation occurs at all protonation levels. Ageing in solution and dilution experiments indic ate that solvation effects, probably rigid rod to coil, occur on a rel atively long time scale.
