I have synthesized tetraaniline, and now I want to dope it. I have some experiences with polyaniline, but I have never tried to dope it.
I am not sure what kind of counterion must be employed during doping, or on what basis we choose it. I know that the counterion is chosen based on the polymerization method, but still there are several options available.
If anyone knows a good reference on doping of polyaniline, that is much appreciated.
