Sign-alternating optical reorientation in nematic liquid crystals with low-molar-mass and polymeric absorbing bis-azobenzene dopants
Original language description
A comparative study of optical orientation in nematic liquid crystals (NLCs) doped with a low-molarmass bis-azobenzene dye (monomer) and a comb-shaped polymer with side fragments similar in structure to the monomer has been carried out. Both types of bis-azobenzene dopants induced a signalternating nonlinearity in the NLC. The magnitudes of the optical-torque enhancement factors due to trans- and cis-isomers, and their ratios for the low- and high-molar-mass dopants are compared. The results obtained show the possibilities of increasing the orientational optical nonlinearity when passing from low-molar bis-azobenzene dye dopants to the corresponding polymers and are important for elucidating the optimal architecture of absorbing additives.
