The invention provides high workfunction p-doped electrically conductive materials comprising one or more triarylaminium moieties counter-balanced by covalently bonded anions, and optionally further comprising one or more non-covalently attached cations. These materials can be used as hole-injection and hole-extraction layers to provide ohmic contacts to semiconductors with deeper ionization potentials than previously possible, up to the workfunction of the material.
