Liquid Crystals Align Liquid Crystals
Japanese Journal of Applied Physics, 2002We 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 ...

Liquid Crystals and Liquid Crystal Solutions Studied By NMR
1999Abstract 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 ...

We report a dielectrically actuated liquid crystal (LC) pump. A small volume of LC forms a pillar-like droplet in a cylindrical hole which partially touches the bottom substrate with embedded interdigitated electrodes. By applying a voltage, the LC droplet can be largely stretched along the electrode direction by the generated dielectric force, which ...

LIQUID CRYSTAL MATERIALS AND LIQUID CRYSTAL DISPLAYS
Annual Review of Materials Science, 1997▪ Abstract Since the early 1970s, three major prerequisites have brought the success of the liquid crystal display (LCD) technology to its key role of today. Namely, the discovery of electro-optical field-effects on which the displays are based, the successful search for liquid crystals (LCs) with material properties that meet the complex ...

Nucleation in liquid crystals and liquid crystal polymers
The Journal of Chemical Physics, 1991A nematic mixture that undergoes a first-order phase transition to an ordered state is considered. The dynamics of the phase separation in terms of a theory based on a time-dependent Landau–Ginzburg equation is described. The laws of growth and dissolution for isotropic and anisotropic droplets are discussed.

Polymer liquid crystals-liquids or crystals
1993Liquid 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/.

Ionic liquid crystals (ILCs) are emerging as interesting materials since they are expected to combine together the technological properties of ionic liquids (ILs) and liquid crystals (LCs). In this chapter, we will present a survey of the literature of the last 5 years, from 2005 to mid-2010 concerning ILCs.

Metallomesogens based on d-block metals are extremely complex dynamic materials, proposed as good candidates in luminescent applications due to the combination of excellent photophysical properties with properties deriving from liquid crystals (self-healing, order and mobility).
