Аннотация: Processes of light-induced reorientation of nematic liquid-crystalline molecules induced by the addition of low concentrations (0.1-2.0 wt %) of comb-shaped polymers and carbosilane dendrimers containing azobenzene fragments are studied. When the molecular structure of the above compounds becomes more complicated, the induced orientational nonlinearity increases. The introduction of 2G and 3G dendrimers into a nematic has for the first time made it possible to visualize and study a purely optical first-order Freedericksz transition in the field of a linearly polarized wave.ISI Document Delivery No.: 808GV Times Cited: 3 Cited Reference Count: 34 Budagovsky, I.
