Paper Abstract

Metal-organic ionic smectices (MOIS) have investigated to find their photorefractive properties. For the first time the multiplexing holographic recording of permanent gratings is obtained in pure lyotropic MOIS. It is proposed new mechanism of holographic recording in ionic smectics involving photo-chemical processes associated with multi-photon absorption. Dynamic grating recording has obtained in MOIS doped by electrochromic impurity (viologen) and in ionic smectic glasses composed by decanoate Co2+. A regeneration of viologen from radical state to initial molecule state becomes the main recording mechanism in MOIS with viologen impurity. Electronic absorption of Co2+ determines the recording of dynamic gratings in the ionic smectic glasses.
