Abstract

A spironaphthoxazine (SOFC) molecule that has a reasonably stable merocyanine form was analyzed and its application in rewritable high density optical data storage was discussed. The SOFC-poly(methyl methacrylate) (PMMA) films for imaging micrometer-sized objects in two dimensions utilizing fluorescence as the read-out method were used. The two-dimensional (2D) luminescence images obtained by confocal microscope employing fluorescence as the read-out method and three-dimensional (3D) recording utilizing two-photon technology with a higher storage density of SOFC were also demonstrated. It was concluded that the incorporation of the ferrocene moiety improves the thermal stability of the photomerocyanine form of the spironaphthoxazine significantly.
