| Abstract(in English) | For the holographic recording system of the stepwise two-photon absorption process, the dependence of the holographic efficiency upon the dispersing binder polymer has been measured. In the recording film, the two-photon absorption material is oligothiophene and the energy acceptor is aryl azide. Various films have been prepared by changing the dispersing polymer, where the final reaction occurs, among zeonex, PMMA and photopolymer. The film with the photopolymer has the highest holographic efficiency among the three. It has been found that photopolymer works effectively even for the stepwise two-photon holographic process in addition to the ordinary one-photon process. The energy accepter molecule has been changed from aryl azide into several aryl ketone molecules. The holographic efficiency, the reactivity and the triplet excited states for the molecules are investigated. |
