The synthesis and characterization of side-chain liquid crystalline (LC) polyacrylates containing para-nitroazohenzene (Pn) as mesogenic groups were described. Homopolymers with 3 and 4 carbon atoms in the spacers were non-LC polymers; for homopolymers with 6 carbon atoms in the spacer, nematic LC b
The relaxation of holographic phase gratings was examined to obtain some information about the involved photochemically induced changes. The studies were performed with statistical liquidcrystalline side group copolymers having different concentrations of the azobenzene dye. The formation of mesopha
