Dye‐doped polymer films: From supramolecular photochemistry to the molecular computer

Research News: Hole burning in the spectra of dye‐doped polymer films provides the opportunity for high density data storage, holographic image storage and even five‐dimensional image storage is feasible (three spatial dimensions, frequency, and electric field). The background of the technique and recent progress in the optical data storage with lasers where impressive resolution and grey scales have been achieved (see Figure) is discussed. magnified image
