A deuterium nuclear magnetic resonance investigation of the symmetry and orientational order of the nematic phase of 4-[3,4,5-tris(4-dodecyloxybenzyloxy)benzoyloxy]-4′- (4-dodecyloxybenzoyloxy)-1,1′-biphenyl. A biaxial nematic?

The first compound for which the previously predicted biaxial nematic phase was claimed is 4-[3,4,5-tris(4-dodecyloxybenzyloxy)benzoyloxy]-4′-(4-dodecyloxybenzoyloxy)-1, 1′-biphenyl (I). This assignment was based on the observation of the optical

The effect of rotating the nematic phase of 4-n-pentyl-4′-cyanobiphenyl (5CB) at a frequency ωr about an axis perpendicular to an applied magnetic field has been studied using deuterium NMR spectroscopy. The alignment of the directors produced by

Publikováno v: Synthetic Metals. :381-383

The suitability of tetrahydrotetrathiafulvalene (THTTF) as an organic metal precursor was investigated. In general, the radical-cation salts of THTTF grew with difficulty, were of poor quality, and had low electrical conductivities. The most interest

Freezeout of the electrical resistivity in (BEDT-TTF)2I3below 20 K

Autor: Dieter Schweitzer, M Weger, M Tittelbach, Heimo J. Keller, E. Balthes

Publikováno v: Journal of Physics: Condensed Matter. 5:8569-8578

We have measured the temperature (T) dependence of the resistivity rho of the beta and K phases of (BEDT-TTF)2I3 from 300 K down to Tc ( approximately 1.3 K and approximately 4 K for the beta and kappa phases, respectively). Between 100 K and 20 K, r
