We will described the synthesis and characterization of polymers modified with the addition of azobenzene moieties in their structure. The possible application of these materials in optics and photonic devices will be evaluated. A general scope on the resulting motion of azobenzene isomerization in polymers will be given, showing that the scale range of these movements goes from little reorientation of the azobenzene group to massive motion of polymeric material. The lecture will be divided in three main sections, resultant of the analysis of the three types of motions associated to the photoinduced isomerization process of the azobenzene: the chromophore motion at the first level, the nano-domain motion at the second level, and the third type of motion at an even larger scale; it can be called macroscopic motion.
