The photoinduced cleavage of oxazine heterocycles, connected to macromolecules spin coated on appropriate substrates, occurs efficiently and irreversibly. The products of this photochemical transformation quench effectively the fluorescence of borondipyrromethene (BODIPY) dopants and turn off their emission. This protocol permits the optical imprinting of fluorescent patterns under mild illumination conditions that are impossible to replicate with methods solely based on bleaching.
