A new liquid crystal monomer, the diacrylate of a bis phenyi diazene, was synthesized. It was polymerized to form both unoriented and oriented polymer solids–the latter in the presence of a magnetic field. The millimeter wave birefringence was meas

The synthesis of unsymmetrical phenyl-1,2,4,5-tetrazines containing a cyano group either on the phenyl ring (1a) or the tetrazine ring (11a, 11b) has been accomplished by the introduction of the cyano group after formation of the tetrazine ring. The

Atmospheric compensation has been demonstrated using a liquid crystal light valve as a monolithic, integrated, wavefront sensor-corrector in a closed loop, all-optical configuration. For successful demonstration of this device, liquid crystal candida

The performance of polymer dispersed liquid crystal (PDLC) films was improved markedly by introduction of a monofunctional liquid crystal monomer component into the photopolymerizable solution from which the PDLC was formed by phase separation. Small

Microtubule particles and metal-coated microtubules were dispersed in various host liquid crystal mixtures. Dispersion effects were evaluated as a function of liquid crystal type, viscosity, dielectric anisotropy and surface interaction. Experimental

A new technique for tilted-perpendicular alignment (TPA) of liquid crystals on surfaces greatly improved the photostability of the photoactivated liquid crystal light valves (LCLVs) with negative dielectric anisotropy liquid crystals. The operation o
