Notes:
In the electro-oxidative preparation of polypyrrole films from electrolyte media containing both perchlorate and hexafluorophosphate anions a striking selectivity towards ClO4 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 PF6 to bolster electrolysis parameters will less readily carry over into the final polymer. PF6 is particularly useful for this purpose in MeCN, where ClO4 is inappropriate, being itself too readily incorporated into the polymer from this solvent system.
