A fluorescent diarylethene derivative that links to a perylene bisimide unit is synthesized and its photochromic and fluorescence properties are studied. Aggregate formation was controlled by the photochromic reaction of the diarylethene unit, and aggregate formation induced a fluorescence wavelength shift between green and red, as shown in the figure.
