Embodiment 1
[0150]
[0151]
[0152] As can be seen from Comparative Examples and Example 1, 5BB(3F)B(3F,5F)CF 2 OB(3F,4F,5F), 4BB(3F)B(3F,5F)CF 2 OB(3F,5F)OCF 3 Replace equal parts with 5BBB(3F,5F)CF 2 OB(3F,4F,5F), 4BBB(3F,5F)CF 2 OB(3F,5F)OCF 3 , the bijection Δn increases, the clearing point Cp increases, and the rotational viscosity γ1 basically remains the same. The mixture provided by the invention exhibits a higher range of liquid crystal phases and a higher refractive index, and is excellent in the application of liquid crystals with low cell thickness and fast response (requiring large birefringence Δn) and wide temperature liquid crystals.
[0153] Due to Example K 11 Larger, despite roughly equivalent viscosities, also achieve faster response times.
Embodiment 2
[0158]
[0159]
[0160] Example 2 has higher refractive index Δn, higher clearing point Cp, higher dielectric anisotropy Δε and higher K than Comparative Example 2 11 .
Embodiment 3
[0165]
[0166] Example 3 has higher refractive index Δn, higher clearing point and higher K than Comparative Example 3 11 .
