用（1 S）-（+）-或（1 R）-（-）-10-邻苯二磺酸（HCSA）掺杂的翠绿亚胺碱在各种溶剂（NMP、DMF、DMSO或CHCl 3）中的溶液通过浇铸获得光学活性聚苯胺盐（PAN/HCSA）膜。分别使用（+）-和（-）-HSA得到的盐膜的镜像圆二色光谱表明掺杂过程中的对映选择性。第一个光学活性环取代的聚苯胺，即聚（邻甲苯胺）/（+）-HCSA和聚（邻甲苯胺）/（-）HCSA，也已经在溶液中通过类似的掺杂程序在DMSO中制备成膜。
Films of optically active polyaniline salts (PAN/HCSA) have been obtained by casting from solutions of emeraldine base doped with (1S)-(+)- or (1R)-(−)-10-camphorsulfonic acid (HCSA) in various solvents (NMP, DMF, DMSO or CHCl3). The mirror-imaged circular dichroism spectra for the salt films derived using (+)- and (−)-HSA, respectively, indicate enantioselectivity in the doping process. The first optically active ring-substituted polyanilines, namely poly(o-toluidine)/(+)-HCSA and poly(o-toluidine)/(−)HCSA, have also been produced in solution and as films via a similar doping procedure in DMSO.
