Abstract

Poly(phenylene vinylene) structure is one of the chromophore with large two photon absorption (TPA) cross section, which is expected as the materials for high density optical data storage with the TPA induced reaction. Photo-irradiation to a poly(phenylene vinylene) derivative changes the refractive index of the polymer by the magnitude as high as 0.7. The mechanism involves photo-induced electron transfer from the TPA dye to matrix for the reaction of a distyrylarene derivative. The refractive index of the polymer also can be changed by the electron beam irradiation.
