Photo-orientation processes in liquid crystalline polymethacrylates with side azobenzene groups having lateral methyl substituents
Original language description
Design of new photoactive materials exhibiting nano-organization aimed for smart practical applications remains an actual and highlighted task. Synthesis and comparative study of chiral LC polymethacrylates with azobenzene groups were carried out to contribute to better understanding of the structure-property relationship. The effect of chirality and length of spacer of the terminal alkyl groups on the photooptical properties were established. The presence of lateral methyl substituent in the photochrome/mesogen fragment leads to a significant decrease of isotropization temperature. The photoorientation processes under illumination with the polarized visible light (457 nm) are studied for amorphousized films. It was found that an increase in the spacer length leads to an increase in the value of photoinduced dichroism (ΔD=0.28). Chirality plays significant role on relaxation behavior of the irradiated enantiopure and racemic films of polymer with long spacer and alkyl tail.
