The self‐assembly of an amphiphilic monomolecular electron acceptor–donor dyad into electroactive π–π stacked fibrillar structures can be triggered by irradiation with visible light. These fibers, exposing hydrophilic ethylene glycol in their external shell, show unique characteristics as resistive humidity sensors that exhibit high sensitivity and ultrafast response.
