Charge carriers: The p ‐doping of self‐doped poly(anilineboronic acid) (PANI‐BA) is studied by in situ electron spin resonance (ESR)/ultraviolet/visible/near‐infrared (UV‐vis‐NIR) spectroelectrochemistry with respect to the role of the ionic side group at the aniline core (see figure). The results point to a primary polaron‐pair formation while a polaron is formed with a further increase of the doping level. At higher doping levels, the formation of diamagnetic species is observed.
