Chemical adjustment possibilities in the physical properties of azobenzene polycomplexes with metal

Changes in the physical properties of polymeric composites based on azobenzene by means of chemical modifications of the polycomplexes' structure and composition are investigated. The main emphasis was on the adjustment of characteristics of electro-optical effect observed in these composites. Among the methods of chemical modification for the coordination of metallic ion include changing the dipole moment of the azobenzene fragment and the spacer length connecting the azobenzene fragment to the main polymeric chain. Introduction of the organic dyes in the azobenzene polymeric composites are also considered. Demonstrated flexibility in the properties of the investigated media is important for their practical application as information or optically active media. (C) 2016 Optical Society of America
