In the large family of polymers, the azobenzene derivatives represent one fascinating materials class, along with
stylbene and azomethinic derivatives. This interest is explained by combination of the properties of anisotropy with the
photoinduced behaviors. The photoinduced birefringence, relief grating, the high optical nonlinearity resulted from the
sin-anti isomerism, molecular reorientation, the exceptional stability to writing and erasing by laser radiation, are just the
most important arguments for their usage of these polymeric architectures in the NLO field as: LCD, chemical sensing,
devices for storage and transmission of information .
This presentation covers the development and characterization a new series of materials from viewpoint of:
-Modification of the polymer materials by the chemical transformation of the "common" polymer support an
underlining: photorefractivity, NLO properties
-Utilization of these polymers as components in guest-host materials preparation.
