The reversible photochemical conversion between the open form 1 , a strong fluorophore, and the closed form containing a central, hexyl‐substituted six‐membered ring, which fluoresces only weakly, makes modulation of emitted light possible. This readily adjustable system is of interest for optical data storage. R = CH 3 + , counterion = CF 3 SO 3 − .
