Long Title: IUPAC Gold Book - proton doping

Status: current

Definition
Transformation of a semiconducting or insulating material to conducting state by protonation (hydronation) of its molecules.

Note
The proton doping is crucial for polyanilines that are good conductors only in the protonated state. Deprotonation (dehydronation), as a reverse transformation is achieved by treating the doped polymer with an alkali.
