Zero-Field Nuclear Magnetic Resonance of a Nematic Liquid Crystal

appear which matched those observed by Sanchez and Spiro. Figure 9 shows the time development of the observed Raman spectrum at -0.8 V which at long times became the spectrum of high-spin Fe(I1). The time development of the spectroscopic changes at -0.8 V contrasts the instantaneous changes observed in the reduction of adsorbed hemin and instead tracks the slow reduction of the entire solution ...

Polarised photoluminescence from oriented polymer liquid crystal films

Optical anisotropy in a new form of crosslinked liquid crystal network incorporating a fluorescent chromophore has been demonstrated. Linearly polarised absorption and fluorescence is observed in oriented thin films. From measurement of absorption and fluorescence anisotropy, the order parameter was found to be 0.65 and 0.80, respectively. Temperature dependent birefringence measurements reveal...

Magnetic-field induced isotropic to nematic liquid crystal phase transition.

We report on measurements of magnetic-field induced nematic order in the bent-core liquid crystal 4-chlororesorcinol bis[4-(4-n-dodecyloxybenzoyloxy) benzoate]. Using the 31 T solenoid at the National High Magnetic Field Laboratory, we have observed, at temperatures less than 1 degrees above the clearing point, a first-order transition to the nematic phase. The critical magnetic field at which ...

Optimizing the Nematic Liquid Crystal Relaxation Speed by Magnetic Field

Nematic liquid crystalline materials have been widely used in electro-optical control of visible light. However, when IR light is considered, the thickness of the liquid crystal layer must be increased which causes the relaxation time of the material to be slower than required for many applications. In this paper we use a magnetic field to increase the speed of thick nematic devices. We show th...

Extensional Flow of Nematic Liquid Crystal under Electric Field Gradient

Systematic asymptotic methods are used to formulate a model for the extensional flow of a thin sheet of nematic liquid crystal. With no external body forces applied, the model is found to be equivalent to the socalled Trouton model for Newtonian sheets (and fibers), albeit with a modified “Trouton ratio”. However, with a symmetry-breaking electric field gradient applied, behavior deviates from ...
