Optoelectronic devices combining the high electrical performances of carbon nanotubes with the remarkable optical properties of polymers are demonstrated (see figure). Photoinduced, λ‐dependent, robust, and reversible modulation of the device conductance is achieved. The optical response is based on the trapping of photoexcited electrons at the polymer dielectric interface. Such a nanotube‐based device proves a very sensitive probe to study the dynamics and spatial distribution of charges in polymers.
