A novel spironaphthoxazine SOFC molecule with a stable ring-opened photomerocyanine form by incorporating a ferrocene moiety to the parent spironaphthoxazine has been synthesized. Two-dimensional luminescence images obtained by confocal microscope employing fluorescence as read-out method (see Figure) and three-dimensional high-density recording using two-photon technology of SOFC-poly(methyl methacrylate) films are demonstrated.
