Get turned on : Fluorescent photochromic organic nanoparticles (FPONs) of 1 (see picture) show a strongly enhanced fluorescence emission with increasing concentration and bistable photochromism. High‐contrast on/off fluorescence switching has been successfully implemented in size‐tuned FPONs of 1 and also in a photo‐rewritable polymer film highly loaded with 1 .
