An efficient approach is demonstrated for preparing functional organic field‐effect transisotrs (OFETs) by using spiropyran‐ co ‐methyl methacrylate (MMA) as the photoactive gate dielectric. These OFETs are capable of photomodulating the carrier density in the conductive channel, thereby resulting in high responsivity.
