Pushing to longer wavelengths: Photochromic inorganic/organic thin films consisting of polyoxomolybdate and alkylammonium ions have been fabricated by a self-assembly process. Characterization of the films reveals a lamellar nature. Proton transfer between the alkylammonium ions and the MoO6 octahedra is suggested to be responsible for the photochromic behavior (see graphic) centered around 472 nm, a longer wavelength than normally accessible with transition-metal thin films.
