Abstract:<\/p>\n

 <\/p>\n

The method of the synthesis of the first representative of azo-azomethine-containing fluorinated polymer is developed. The main peculiarity of the obtained polymer is the combination of azo- and azomethine groups within one conjugated unit, which is separated by an aliphatic spacer and a trafluor-1,4-oxyphenylene block. The synthesized polymer is characterized as well dissolved in ionic liquids, based on N,N\u2013dialkylimidazolium salts, not dissolved in organic solvents and resistant to the acid and alkali impact.<\/em><\/p>\n

The structural investigations have shown that azo-azomethine-containing fluorinated polymer has an amorphous crystalline structure, its degree of crystallinity makes up approximately 50%. It has been established that the investigated polymer is a thermostable polymer and its glass transition temperature does not emerge right up to 300\u00a0\u00b0<\/em>\u0421<\/em>. The peculiarities of the photo-optical behavior of obtained polymer have been modeled and studied from the example of an azo-azomethine containing chromophore specimen. Its structure completely reflects the structure specificity of the repeated unit in the obtained polymer. It is shown that the synthesized azo-azomethine containing chromophore is characterized by high optical sensitivity and is able to perform photoisomerization under the influence of UV-irradiation. In doing so, the photostationary state for it comes after 30 sec of irradiation. The synthesized compounds are extremely interesting for creating the thermostable photo-active materials with nonlinear optical and liquid crystal properties.<\/em><\/p>\n
