Abstract: of vapor-doped films was attributed to the increased carrier concentrations without degradation of mobilities, which indicates that vapor doping enables more effective doping reactions with maintained crystallinity, compared with solution doping, because acid vapor molecules directly diffuse into the polar side chains of pure polymers as confirmed by grazing-incidence wide-angle X-ray scattering. Moreover, TfOH-doped films exhibited exceptional air stability stored in air for over one month. This work demonstrates that TfOH vapor doping without ultrahigh vacuum conditions represents a promising approach for improving the electrical conductivity and stability of conductive polymers for flexible electronics.
