Photoactivatable synthetic fluorophores
The concatenation of a photochemical transformation with a photophysical process can be exploited to activate the fluorescence of synthetic chromophores under optical control. The resulting photoactivatable fluorophores permit the monitoring of dynamic processes in real time and the reconstruction of images with spatial resolution at the nanometer level.

Activation of BODIPY fluorescence by the photoinduced dealkylation of a pyridinium quencher
The photoinduced transformation of a pyridinium cation into a pyridine ring suppresses electron transfer from an adjacent BODIPY fluorophore upon excitation and activates the emission of the latter.
