Embodiment Construction
[0145] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited to the following examples. The methods are conventional methods unless otherwise specified. The raw materials can be obtained from open commercial channels unless otherwise specified.
[0146] The percentages in this manual are percentages by mass, and the temperature is in degrees Celsius (°C). The specific meanings and test conditions of other symbols are as follows:
[0147] Cp means liquid crystal clearing point (℃), DSC quantitative method test;
[0148] S-N represents the melting point (°C) from the crystalline state of the liquid crystal to the nematic phase;
[0149] Δn denotes optical anisotropy, n o is the refractive index of ordinary light, n e is the refractive index of extraordinary light, the test condition is 25±2°C, 589nm, Abbe refractometer test;
[0150] Δε means dielectric anisotropy, Δε=ε ∥ -ε ⊥ , where ε ∥ is ...
