Strong evidence of fluoride substitution on the pyrrole ring during electrolysis has been observed in a systematic structural and thermal analyses of polypyrrole doped with BF 4 – by direct insertion probe‐mass spectrometry. To get a better understanding, not only polypyrrole samples doped with different dopant levels but also dedoped polypyrrole samples, mechanical mixtures of undoped polypyrrole and N(Bu) 4 BF 4 were analyzed using pyrolysis mass and FTIR spectroscopy techniques.
