Description

WORKING EXAMPLES

[0326] The following examples are intended to explain the invention without limiting it. In the examples, m.p. denotes the melting point and C denotes the clearing point of a liquid-crystalline substance in degrees Celsius; boiling points are denoted by b.p. Furthermore:

[0327] C denotes crystalline solid state, S denotes smectic phase (the index denotes the phase type), N denotes nematic state, Ch denotes cholesteric phase, I denotes isotropic phase, T.sub.g denotes glass-transition temperature. The number between two symbols indicates the conversion temperature in degrees Celsius.

[0328] The host mixture used for determination of the optical anisotropy n of the compounds of the formula I is the commercial mixture ZLI-4792 (Merck KGaA). The dielectric anisotropy is determined using commercial mixture ZLI-2857. The physical data of the compound to be investigated are obtained from the change in the dielectric constants of the host mixture after addition of the compound to be investigated and extrapolation to 100% of the compound employed. In general, 10% of the compound to be investigated are dissolved in the host mixture, depending on the solubility.

[0329] Unless indicated otherwise, parts or percent data denote parts by weight or percent by weight.

[0330] Above and below, [0331] V.sub.o denotes the threshold voltage, capacitive [V] at 20 C. [0332] n denotes the optical anisotropy measured at 20 C. and 589 nm [0333] denotes the dielectric anisotropy at 20 C. and 1 kHz [0334] T.sub.(N,I) denotes the clearing point [ C.] [0335] K.sub.1 denotes the elastic constant, splay deformation at 20 C. [pN] [0336] K.sub.3 denotes the elastic constant, bend deformation at 20 C. [pN] [0337] .sub.1 denotes the rotational viscosity measured at 20 C. [mPa.Math.s], determined by the rotation method in a magnetic field [0338] LTS denotes the low-temperature stability (nematic phase), determined in bulk samples.

[0339] The display used for measurement of the threshold voltage has two plane-parallel outer plates at a separation of 20 m and electrode layers with alignment layers comprising SE-1211 (Nissan Chemicals) on top on the insides of the outer plates, which effect a homeotropic alignment of the liquid crystals.

[0340] In order to determine the low-temperature stability (nematic phase), samples (typically 2 g) are stored in glass vials at the temperature indicated and investigated visually daily for the occurrence of crystallisation or smectic phases. The time indicated in the tables is the time after which a phase conversion was observed for the first time. The test is terminated after 1000 h and LTS: 1000 noted.

[0341] All concentrations in this application, unless explicitly indicated otherwise, relate to the corresponding mixture or mixture component. All physical properties are determined in accordance with Merck Liquid Crystals, Physical Properties of Liquid Crystals, status November 1997, Merck KGaA, Germany, and apply for a temperature of 20 C., unless explicitly indicated otherwise.
