The 1D nanostructures of perylenediimides (PDIs) have been readily obtained owing to strong cofacial π–π stacking interactions, which, however, subsequently render PDIs weakly emissive in the solid state. Therefore, organic solid‐state lasers based on 1D nanostructures of PDIs have not been achieved yet. Herein, we prepared 1D‐nanowires of N,N’‐bis(1‐ethylpropyl)‐2,5,8,11‐tetrakis( o ‐methylphenyl)‐perylene‐3,4:9,10‐tetracarboxylic acid diimide (mp‐PDI), which stack into a loosely J‐type arrangement. J‐aggregation leads to a solid‐state photoluminescence (PL) efficiency φ >18 % and the nanowires of mp‐PDI exhibit excellent Fabry–Perot (FP) mode laser action.
