Liquid crystalline compounds and mixtures. Inukai, Takashi; Furukawa, Kenji; Terashima, Kanetsugu; Saito, Shinichi (Chisso Corp. , Japan). Eur. Pat. Appl. EP 115693 A2 15 Aug 1984, 33 pp. DESIGNATED STATES: R: CH, DE, FR, GB, LI. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C09K003-34. APPLICATION: EP 83-307884 22 Dec 1983. PRIORITY: JP 83-640 6 Jan 1983; JP 83-78594 4 May 1983. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 25, 73, 75, 76 Chiral smectic compds. of the formula I (R = C1-18 linear or branched alkyl or alkoxy; R1 = optically active alkyl; Z = 1,4-phenylene or 1,4-trans-cyclohexylene; m = 0, 1, or 2; n = 1 or 2), which have a superior stability, are described for use in liq. crystal compns. for electrooptical display devices. Thus, a liq. crystal compn. contg. 50909-50-7 is also in the experiment. I (R = C6H3O; R1 = 2-methylbutyl; Z = 1,4-phenylene; m = 0; n = 2) 20, I (R = C8H17O; R1 = 2-methylbutyl; Z = 1,4-phenylene; m = 0; n = 2) 20, I (R = C7H15O; R1 = 2-methylbutyl; Z = 1,4-phenylene; m = 1, n = 2) 10, I (R = C9H19O; R1 = 2-methylbutyl; Z = 1,4-phenylene; m = 1; n = 2) 10, I (R = C16H33O; R1 = 2-methylbutyl; Z = 1,4-phenylene; m = 1;, n = 2) 10, and I (R = C8H12O; R1 = 2-methylbutyl; Z = 1,4-phenylene, m = 1; n = 2) 10 parts exhibited a chiral smectic C phase ￡70°, a cholesteric phase 370°, and become isotropic at 105°. After addn. of an anthraquinone dye (D-16) 3%, this compn. was placed in a display cell and an a.c. of 15 V (0.5 Hz) was applied to show a very good contrast and a high response rate (￡1 ms).Except for chemicals metioned above, 50909-50-7 is also used. ..
