Doping‐induced solubility control is a patterning technique for semiconducting polymers, which utilizes the reduction in polymer solubility upon p‐type doping to provide direct, optical control of film topography and doping level. In situ direct‐write patterning and imaging are demonstrated, revealing sub‐diffraction‐limited topographic features. Photoinduced force microscopy shows that doping level can be optically modulated with similar resolution.
