(a) Transmittance intensities of an orientated sample of CCN-47 doped with C153 under crossed polarizers as a function of temperature. (b) Schematic illustration of light-induced anchoring transition and bistability.
POM images of LC textures showing anchoring transitions in the cooling (left) and heating (right) processes.
(a) POM image of recorded line patterns. (b) POM image of recorded LC pattern.
Transition temperatures as a function of the concentration of CP7B in the CCN-47/CP7B binary mixture system. Iso and N stand for isotropic and nematic phases, respectively. The area between triangular and circular symbols represents bistable regime, i.e., both planar and homeotropic alignments are stable.
