Evergrowing interest to LC-polymers is connected with their combination of unique optical properties, such as birefringence, high optical rotation, selective reflection, circular dichroism and ability to form a “frozen” glassy state, in the form of stable coatings and films. LC-polymers with photovariable optical properties attract a special attention due to their potential application for optical devices and optical data storage. In this presentation different approaches for development of a novel family of multifunctional polymeric materials with photocontrollable supramolecular structure and optical properties will be discussed. The main idea of design of these materials is based on copolymerization of different functional monomers. For this purpose the different types of monomers were synthesized and copolymerized, including nematogenic monomers responsible for the mesophase formation, chiral monomers inducing helical twisting, photochromic and chiral-photochromic monomers which are capable for photoisomerizing. In addition, a number of hydrogen-bonded polymer mixtures containing crown-ether derivatives complexing with metal cations were obtained and their photooptical properties are discussed.
