Abstract
Comparative study of chiro- and photo-optical properties of three novel chiral photochromic liquid crystalline azobenzene-containing comb-shaped polyacrylates was performed. The synthesized polymers contain the same polyacrylate backbones and uniform spacer size (10 methylene units), but have different structure of azobenzene-containing mesogenic groups with different chiral tail. The polymers are characterized by crystalline, SmA*, SmC*, and N* phases formation depending on chemical structure of the variable fragments. Presence of the lateral chlorine substituent in the mesogen fragment leads to an extreme decrease of isotropization temperature and causes a disappearance of cholesteric mesophase. Circular dichroism (CD) spectra demonstrate formation of helical order elements even in the amorphousized spin-coated polymer films. Possibility of manipulation of CD values and degree of the helical order by light and annealing was established and studied. UV-irradiation of all polymers induces E–Z isomerizatio...
