Fig. 19 Phase transition behaviour of the mixture of 22 and the LC 4-pentyl-4 -(cyano)biphenyl (nematic 24-35 °C) as a function of their molar ratios and proposed structure for the molecular aggregates...

Fig. 7. Arrhenius plots of diffusion constants of nematic and isotropic pentyl-alkyl-cyano-biphenyl SCB (upper) and pentyl-alkyloxy-cyano-biphenyl 50CB (lower) to illustrate the quality of the Arrhenius law, the anisotropy ratio and the changes due to the slightly different side-groups of the two cyano-biphenyls. The data cannot be interpreted with existing theories. ...

In the experiment reported in reference [25], the liquid crystal used is a 150 pm planar aligned dye-doped 5CB (Pentyl-Cyano-Biphenyl) cell... 

Sandmann, M., Hamaim, R, and Wiirflinger, A., PVT measurements on 4-n-pentyl-4 -cyano-biphenyl (5CB) and frafw-4-(4 -octyl-cyclohexyl)- benzonitrile (8PCH) up to 300 MPa, Z Naturforsch., 52a, 739-747 (1997). 

At present, the purely optically induced molecular reorientation has been observed in a few well known NEC s, such as 5CB (pentyl-cyano-biphenyl), 8CB (octyl-cyano-bi-phenyl), and MBBA (p-/i-methoxybenzilidene-/7-bytylani-line). " The influence of a superposed electric field on 7,h has been experimentally verified by Csillag et a/., using 8CB w > 0) and MBBA [w < 0). Since all the NEC s used in the experiments have positive values of Bq and 8CB does not satisfy 0single component nematic PAA (p-azoxyanisole) at 110-130 C. This prediction has not been verified experimentally. By examining data on rtioW existing NEC s (up to a few hundred), we have...
