Photoalignment of Liquid Crystals by Liquid Crystals

Physical Review Letters, 2000
We observed light-induced alignment of the nematic liquid crystal, 4, 4(')-n-pentylcyanobiphenyl (5CB), on a fused quartz. Irradiation of the adsorbed layer with polarized ultraviolet light produced homogeneous alignment in a 5CB-filled liquid crystal cell with the easy orientation axis perpendicular to the polarization direction.

Liquids, Crystals and Liquid Crystals

Physics Today, 1989
In thinking about the states of condensed matter, we usually consider two extremes. At one extreme are crystalline solids, in which atoms form a perfectly periodic array that extends to infinity in three directions. At the other extreme are fluids or glasses, in which the atoms or molecules are completely disordered and the system is both ...

Liquid Crystals and Liquid Crystal Solutions Studied By NMR

1999
Abstract Since the first publication on this subject in 1963, {NMR} in liquid crystalline systems has been a wide and active field of research in many branches of chemistry, physics, biology, and materials science. Indeed, thanks to the wealth of exploitable nuclei and interactions, {NMR} spectroscopy has revealed a powerful means of probing structure ...

Liquid Crystals Align Liquid Crystals

Japanese Journal of Applied Physics, 2002
We have investigated the molecular orientation of a liquid crystal (LC), pentylcyanobiphenyl (5CB), evaporated on a rubbed polymer by means of polarized ultraviolet absorption spectroscopy and surface second-harmonic generation. The results unambiguously reveal that the in-plane anisotropy is diminishingly small before the molecules form a monolayer ...

Polymer liquid crystals-liquids or crystals

1993
Liquid crystals belong to a class of materials which were first described over a hundred years ago as characterising a state of matter intermediate between that of a crystal and a liquid. The light microscopic textures which are observed in these “ordered liquids” are very characteristic and have been described in many text books /1/.
