Novel Progress in Rewritable High Density Optical Data Storage

In collaboration with colleagues in the University of Sciences and Technology of China and East China University of Science and Technology, CAS researchers from the Institute of Chemistry have synthesized a novel spironaphthoxazine SOFC molecule with a stable ring-opened photomerocyanine form by incorporating a ferrocene moiety to the parent spironaphthoxazine. Their work has been reported in a recent issue of Advanced Materials.

The researchers say that two-dimensional luminescence images obtained by confocal microscope employing fluorescence as read-out method and three-dimensional high-density recording using two-photon technology of SOFC-PMMA films were displayed. It is the first example of realization of the practical information storage utilizing spirooxazine derivatives. They suggest that, considering its inherent reversible photoisomerization and high fatigue resistance, SOFC can be a promising candidate for storage of optical information with an ability of repeated "re-recording".
