This alternative approach has also been successfully employed to produce optically active polyanilines. The use of optically active dopant anions such as (H-) - or ( - ) - camphorsulfonate (CSA ) [37-39], (-i-)-or( —) - tartrate [40] and related chiral anions induces macroasymmetry in to the polyaniline chains. We [41] and others [42] have recently shown that films of optically active polyaniline salts such as PAn( -1- )-HCSA, or the optically active emeraldine base (EB) derived from them, exhibit chiral discrimination towards chiral chemicals such as the enantiomers of CSA and amino acids.
