Conducting polymers that contain host–guest complex units have been synthesized by electropolymerization of bis‐(bithiophene)‐substituted tungsten‐capped calixarenes (see Figure for general formula). The guest molecule, weakly bonded to the tungsten atom, participates in electron transport. Hence, the conductivity depends on the guest’s chemical nature, making the polymer potentially useful as a small‐molecule sensor.
