Embodiment 1
[0130] 15% 2CC B(3F,5F)BOCF in Comparative Example 1 3 Replaced with 8% 5CBB(3F,5F)BCF 3 +7% of 3CBB(3F,5F)BCF 3 , obtain embodiment 1 composition:
[0131] Δε[1KHz,20℃]: 10.5
[0132] Δn[589nm, 20°C]: 0.120
[0133] K 11 : 13.5
[0134] Cp: 120°C
[0135] gamma 1 : 140mPa.s.
[0136] Obviously, the γ of the liquid crystal in Example 1 1 Decrease, Δn, K 11 All have been improved, especially suitable for low cell thickness and fast response liquid crystal.
Embodiment 2
[0140] In comparative example 2, 7% of 3CCB(3F)B(3F,4F,5F) was replaced with 7% of 5CBB(3F,5F)BCF 3 , 9% of 5CCB(3F,5F)BF is replaced by 9% of 5CBB(3F,5F)BCF 3 ,, obtain embodiment 2 composition:
[0141] Δε[1KHz,20℃]: 5.5
[0142] Δn[589nm, 20°C]: 0.105
[0143] Cp: 135°C
[0144] gamma 1 : 150mPa.s.
[0145] Obviously, the γ of the liquid crystal in Example 1 1 Δn and Δε are improved, especially suitable for low cell thickness and fast response liquid crystal.
