Non-resonant two-photon absorbing material, non-resonant two-photon emitting material, and method for inducing absorption or generating emission of non-resonant two photons by using the material

摘要

A non-resonant two-photon absorbing material is provided, comprising a methine dye undergoing a non-resonant two-photon absorption, in which the methine dye is preferably a cyanine dye, a merocyanine dye or an oxonol dye, and a non-resonant two-photon absorbing material is provided, comprising a non-resonant two-photon absorbing compound undergoing non-resonant two-photon absorption in the intermolecular aggregation state.
