Description

WORKING EXAMPLES

[0520] 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 temperatures are denoted by m.p. Furthermore: 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.

[0521] The host mixture used for determination of the optical anisotropy Δn of single compounds is the commercial mixture ZLI-4792 (Merck KGaA). The dielectric anisotropy Δε 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.

[0522] Unless indicated otherwise, parts or percent data denote parts by weight or percent by weight.

[0523] Above and below: [0524] V.sub.o denotes threshold voltage, capacitive [V] at 20° C., [0525] n.sub.e denotes extraordinary refractive index at 20° C. and 589 nm, [0526] n.sub.o denotes ordinary refractive index at 20° C. and 589 nm, [0527] Δn denotes optical anisotropy at 20° C. and 589 nm, [0528] ε.sub.⊥ denotes dielectric permittivity perpendicular to the director at 20° C. and 1 kHz, [0529] ε.sub.∥ denotes dielectric permittivity parallel to the director at 20° C. and 1 kHz, [0530] Δε denotes dielectric anisotropy at 20° C. and 1 kHz, [0531] cl.p., T(N,I) denotes clearing point [° C.], [0532] γ.sub.1 denotes rotational viscosity measured at 20° C. [mPa.Math.s], [0533] K.sub.1 denotes elastic constant, “splay” deformation at 20° C. [pN], [0534] K.sub.2 denotes elastic constant, “twist” deformation at 20° C. [pN], [0535] K.sub.3 denotes elastic constant, “bend” deformation at 20° C. [pN], [0536] K.sub.avg. denotes average elastic constant defined as K.sub.avg.=1/3(1.5K.sub.1+K.sub.3) [0537] LTS denotes low-temperature stability (nematic phase), determined in test cells or in the bulk, as specified.

[0538] Unless explicitly noted otherwise, all values indicated in the present application for temperatures, such as, for example, the melting point T(C,N), the transition from the smectic (S) to the nematic (N) phase T(S,N) and the clearing point T(N,I) or cl.p., are indicated in degrees Celsius (° C.). M.p. denotes melting point. Furthermore, Tg=glass state, C=crystalline state, N=nematic phase, S=smectic phase and I=isotropic phase. The numbers between these symbols represent the transition temperatures.

[0539] The term “threshold voltage” for the present invention relates to the capacitive threshold (V.sub.0), also called the Freedericksz threshold, unless explicitly indicated otherwise. In the examples, as is generally usual, the optical threshold can also be indicated for 10% relative contrast (V.sub.10).

[0540] The display used for measurement of the capacitive threshold voltage consists of two plane-parallel glass outer plates at a separation of 20 μm, which each have on the insides an electrode layer and an unrubbed polyimide alignment layer on top, which cause a homeotropic edge alignment of the liquid-crystal molecules.

[0541] The display or test cell used for measurement of the tilt angle consists of two plane-parallel glass outer plates at a separation of 4 μm, which each have on the insides an electrode layer and a polyimide alignment layer on top, where the two polyimide layers are rubbed antiparallel to one another and cause a homeotropic edge alignment of the liquid-crystal molecules.

[0542] Unless indicated otherwise, the VHR is determined at 20° C. (VHR.sub.20) and after 5 minutes in an oven at 100° C. (VHR.sub.100) in a commercially available instrument Model LCM-1 (O0004) from TOYO Corporation, Japan. The voltage used has a frequency of in a range from 1 Hz to 60 Hz, unless indicated more precisely.

[0543] The accuracy of the VHR measurement values depends on the respective value of the VHR. The accuracy decreases with decreasing values. The deviations generally observed in the case of values in the various magnitude ranges are compiled in their order of magnitude in the following table.

[0544] The stability to UV irradiation is investigated in a “Suntest CPS+”, a commercial instrument from Heraeus, Germany, using a Xenon lamp NXE1500B. The sealed test cells are irradiated for 2.0 h, unless explicitly indicated, without additional heating. The irradiation power in the wavelength range from 300 nm to 800 nm is 765 W/m.sup.2 V. A UV “cut-off” filter having an edge wavelength of 310 nm is used in order to simulate the so-called window glass mode. In each series of experiments, at least four test cells are investigated for each condition, and the respective results are indicated as averages of the corresponding individual measurements.

[0545] The decrease in the voltage holding ratio (ΔVHR) usually caused by the exposure, for example by UV irradiation or by LCD backlighting, is determined in accordance with the following equation (1):

ΔVHR(t)═VHR(t)−VHR(t=0)  (1)

[0546] In order to investigate the low-temperature stability, also known as “LTS”, i.e. the stability of the LC mixture in the bulk against spontaneous crystallisation of individual components at low temperatures or the occurrence of smectic phases, as the case may be, several sealed bottles, each containing about 1 g of the material, are stored at one or more given temperatures, typically of −10° C., −20° C., −30° C. and/or −40° C. and it is inspected at regular intervals visually, whether a phase transition is observed or not. As soon as the first one of the samples at a given temperature shows a change time is noted. The time until the last inspection, at which no change has been observed, is noted as the respective LTS.

[0547] The ion density from which the resistivity is calculated is measured using the commercially available LC Material Characteristics Measurement System Model 6254 from Toyo Corporation, Japan, using VHR test cells with AL16301 Polyimide (JSR Corp., Japan) having a 3.2 μm cell gap. The measurement is performed after 5 min of storage in an oven at 60° C. or 100° C.

[0548] The so-called “HTP” denotes the helical twisting power of an optically active or chiral substance in an LC medium (in μm). Unless indicated otherwise, the HTP is measured in the commercially available nematic LC host mixture MLD-6260 (Merck KGaA) at a temperature of 20° C.

[0549] The Clearing point is measured using the Mettler Thermosystem FP900. The optical anisotropy (Δn) is measured using an Abbe Refractometer H.sub.005 (Natrium-spectral lamp Na10 at 589 nm, 20° C.). The dielectric anisotropy (Δc) is measured using an LCR-Meter E4980A/Agilent (G005) at 20° C. (c-parallel-cells with JALS 2096-R.sup.1). The turn on voltage (V.sub.0) is measured using an LCR-Meter E4980A/Agilent (G005) at 20° C. (c-parallel-cells with JALS 2096-R.sup.1). The rotational viscosity (71) is measured using a TOYO LCM-2 (0002) at 20° C. (gamma 1 negative cells with JALS-2096-R 1). The elastic constant (K.sub.1, splay) is measured using an LCR-Meter E4980A/Agilent (G005) at 20° C. (c parallel-cells with JALS 2096-R.sup.1). K.sub.3: The elastic constant (K.sub.3, bend) is measured using an LCR-Meter E4980A/Agilent (G005) at 20° C. (s-parallel-cells with JALS 2096-R.sup.1).

[0550] Unless explicitly noted otherwise, all concentrations in the present application are indicated in percent by weight and relate to the corresponding mixture as a whole, comprising all solid or liquid-crystalline components, without solvents. 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.

[0551] The entire disclosures of all applications, patents and publications, cited herein and of corresponding European Application No. EP20183843, filed Jul. 3, 2020, are incorporated by reference herein.

[0552] The following mixture examples having negative dielectric anisotropy are suitable, in particular, for liquid-crystal displays which have at least one planar alignment layer, such as, for example, IPS and FFS displays, in particular UB-FFS(=ultra-bright FFS), and for VA displays.

[0557] Comparative examples C-1 and C-2 are very similar to mixture N-1 in terms of composition, clearing temperature, dielectric anisotropy and birefringence but do not comprise a compound of formula I. The comparison of mixture example N-1 with C-1 and C-2 unexpectedly shows significantly improved (lower) γ.sub.1/K.sub.1 values of the liquid crystalline media according to the invention due to the use of a compound of formula I, which results in faster switching of a display comprising the medium (Table 1). In addition, the value of K.sub.avg is practically unchanged or even higher which corresponds to an unchanged high contrast.
