In the electro‐oxidative preparation of polypyrrole films from electrolyte media containing both perchlorate and hexafluorophosphate anions a striking selectivity towards ClO 4 was observed, with a three‐fold preference for this anion in films from aqueous medium and a greater than ten‐fold preference from MeCN. This result is of benefit towards the production of polypyrroles containing complex functionalized dopant anions, since the presence of PF 6 to bolster electrolysis parameters will less readily carry over into the final polymer. PF 6 is particularly useful for this purpose in MeCN, where ClO 4 is inappropriate, being itself too readily incorporated into the polymer from this solvent system.
