Low colorless for voltage liquid crystal operation and it is low viscosity chemical compound

摘要

It possesses the almost same viscosity as the liquid crystal composition, low the colorless dopant which supports voltage operation is offered. As for this dopant, three structures: (1) biphenyl, (2) diphenyl - jiasechiren and (3) it possesses one among the double tolanes, when it is each one in, the amino group which is connected to the end of one side of the particular molecule (third) it possesses the forks, possesses the polar group of 1 kinds at least in other end of the particular molecule. Outline, the inclusive structure Conversion 1 (Here, R₁ to be the alkyl which possesses 1 - 12 carbon atoms, R₂ to be hydrogen, or or R₁ in independence, to be the alkyl which possesses 1 - 12 carbon atoms, M to be the polar group, X and Y, in independence, hydrogen, or to be the polar group where it is not necessary to be the same as M, as for (A), (1) single bond (biphenyl); (2)-cc-cc- (diphenyl - jiasechiren); Or (3) Conversion 2 (The double tolane) (here, to show hydrogen, F or alkyl) is) with it is possible Z.
