Photochromic monomers and methods for preparing these photochromic monomers, photochromic polymers based on these photochromic monomers and methods for preparing these photochromic polymers, as well as the use of these photochromic polymers in a polymer binder as a two-photon recording medium for an optical 3D memory and photoswitches of optical signals are disclosed. The materials exhibit thermally irreversible photochromic transformations and other properties enabling the use of the photochromic polymers in an optical two-photon read/write memory.
