Photochromic fulgides are UHV‐deposited in ultrathin films exhibiting intrinsic nanostructures. The two isomeric states (C and E) are detected in absorption via scanning near‐field optical microscopy (SNOM). The optical image contrast measured in SNOM corresponds to the nanostructure topography observed in atomic force microscopy. Nano‐optical reversible switching of individual nanostructures is demonstrated and possible applications to rewritable optical recording on the nanoscale are discussed.
