Nematic-smectic-A tricritical point in alkylcyanobiphenyl liquid crystals

Nematic-smectic-A tricritical point in alkylcyanobiphenyl liquid crystals. Thoen, J.Several substances are used for example 41122-71-8 and 52709-85-0 which are their cas registry numbers.; Marynissen, H.; Van Dael, W. (Lab. Molekuulfys., Kathol. Univ. Leuven, Louvain B-3030, Belg.). Phys. Rev. Lett., 52(3), 204-7 (English) 1984. CODEN: PRLTAO. ISSN: 0031-9007. DOCUMENT TYPE: Journal CA Section: 75 (Crystallography and Liquid Crystals) In mixts. of 9CB and 10CB, two compds. of the alkylcyanobiphenyl (nCB) series, the nematic (N) to smectic-A (A) transition becomes 1st order for narrow N ranges. From the latent heats, a tricrit. point is located in the phase diagram. Measurements for 7CB + 8CB mixts. show that the specific-heat exponent a depends on the width of the N range for continuous AN transitions. .

DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 75 The compn. 52709-85-0 and 59454-35-2 are also in the experiment. contains 4-nonyl-4'-cyanobiphenyl, 4-nonyloxy-4'-cyanobiphenyl, 4-decyl-4'-cyanobiphenyl, and/or 4-decyloxy-4'-cyanobiphenyl, and is substantially free from 4-alkyl-4'-cyanobiphenyls and 4-alkyloxy-4'-cyanobiphenyls. The compn. may further contain I (R = C1-15 alkyl) or II (R1 = C1-15 alkyl or C1-15 alkoxy), and a 2-methylalkanoylphenyl deriv. Information recording medium with high contrast is obtained by using the compn. .
