In 1992, Cao et al. [9] from UNIAX company prepared soluble conducting polyaniline (by counteranion induced solubility) and solved the difficulty of processing of conducting polymers, which paved the way for large-scale application of conducting polymers. 1 Effect of Substituents on Solubility of Conjugated Polymers Conjugated polymers without substituents are all insoluble. Attaching appropriate flexible side chains (substituents) can make the conjugated polymers soluble in organic solvents. For example, polythiophene without substituents is insoluble in any solvent, whereas the hexyl-substituted polythiophene derivative P3HT is soluble in organic solvents such as toluene, chlorobenzene, dichlorobenzene, etc.

With the reduction (dedoping) of the conducting polyaniline, the NIR absorption is weakened and finally disappears when it is reduced to its intrinsic conjugated state. Conducting polyaniline can be protonacid dedoped to become a pernigraniline (PAn-III) which shows an absorption spectra with two strong absorption peaks at ca.
