Abstract: The reaction of electrode-confined polyaniline with trifluoroacetic anhydride in acidified acetonitrile giving insulating and electroinactive trifluoroacetylated polyaniline has been studied by electrochemistry, reflectance IR, and microelectrochemistry. Variation of electrochemical potential from 0.2 V (reduced, most reactive) to 0.6 V (oxidized by 0.5 electron per repeat unit, unreactive) vs SCE allows control of the reaction rate. Reaction of ...
