Optical control of the photo‐ and electrochemiluminescence of a brightly fluorescent reporter group is possible by switching between the photochromic units of dyads 1 a and 1 b . Irradiation, that is, writing in information, with UV light converts the highly luminescent dihydroazulene 1 a into the weakly emissive vinylheptafulvene 1 b . Readout of the system can be performed by either electrochemically generated or photogenerated luminescence.
