FIELD: optical physics.

SUBSTANCE: present invention relates to optical physics, in particular, to a method for forming a polarization-sensitive material, capable of forming and/or transforming, in volume thereof and on surface thereof, the spatially modulated picture in the solid state, ordered anisotropic molecular structure in the form of a polarization-optical element. Claimed method of forming a polarization-sensitive material, capable in the solid state reversibly form and/or transform in volume thereof and on the surface a picture of a spatially modulated, ordered anisotropic molecular structure in the form of a polarization-optical element by acting polarized or unpolarized, but directed radiation to the polarization-sensitive component of the specified polarization-sensitive material. As a polarization-sensitive component, responsible for the formation in it of an anisotropic optical element, photochemically stable, anisotropic one- or two-photon absorbing, non-luminescent or weakly luminescent substance is used, which is a component of a polarization-sensitive material in the form of a component uniformly distributed at the molecular level in a homogeneous and isotropic low or high molecular weight matrix. Specified formed spatially modulated, ordered anisotropic molecular structure can be reversibly formed and/or transformed many times both in the case of a single, and in the case of a two-photon, through a real or virtual intermediate level, absorption of the proposed photochemically stable component of the polarization-sensitive material, which also includes other low molecular weight additives whose vibrational levels of the ground state are close or in resonance with the corresponding vibrational levels of molecules of a photochemically stable substance, providing an efficient process of anisotropic intermolecular vibrational cross-relaxation of the energy of an absorbed quantum in the nearest environment during irradiation of the MDL, in addition, the regulatory film-forming, viscous, anisotropic-optical, physico-chemical and mechanical properties of the formed material, depending on its specific application.

EFFECT: technical result: development of a method for forming new polarization-sensitive solid-state photoanisotropic materials based on a previously unknown effect in non-luminescent or weakly luminescent, photochemically stable, anisotropically absorbing (dichroic) substances (pCSS) capable of reversibly forming and/or transforming spatially modulated, ordered molecular functional nano-, micro- or macro-pattern structures in accordance with the spatial distribution of polarization and energy characteristics of one- or two-photon absorbed activating radiation.
