Title:
OPTICAL STORAGE MEDIUM MAKING USE OF OLIGOTHIOPHENE
Document Type and Number:
WIPO Patent Application WO/2006/098296
Kind Code:
A1
Abstract:
A highly efficient two-stage-excited hologram memory or other optical storage medium making use of a compound, such as an oligothiophene compound, that although being high in the efficiency of generation of singlet excited state and triplet excited state, is not apt to immediately induce a chemical reaction involving a structural change, etc.; and an organic composition for production of optical storage medium wherein an organic mixture constituting this optical storage medium is contained. There is provided an optical storage medium of organic mixture characterized by having not only a two-stage-excited energy donor capable of being excited to a singlet excited state by irradiation with a first exciting light, subsequently being transferred to the lowest triplet excited state by intersystem crossing and thereafter being excited to a higher triplet excited state by irradiation with a second exciting light but also an energy acceptor capable of receiving energy from the energy donor and feeding the energy to a chemical reaction.
