Abstract

Abstract : Proton transfer from a photoacid generator to a halochromic molecular switch within a polymer film permits the imprinting of fluorescent patterns under the influence of optical stimulations. Abstract : An indolizine heterocycle switches from a nonemissive to an emissive form upon protonation. The co-entrapment of this molecular switch and a photoacid generator in polymer films allows the imprinting of fluorescent patterns in the resulting materials. These operating principles permit the writing and reading of information under optical control.
