摘要:
Chiral smectic compounds with a high response rate and superior as a ferroelectric liquid crystalline material are expressed by the formula (wherein X represents -CH 2 -, -O- or-CO-; n represents 0. 1 or 2: when X reoresents -CH 2 -. Y recresents R-. R-CO-. ROCO-, wherein R represents an alkyl group having 1 to 18 carbon atoms, and when X represents -0- or-CO-, Y represents R; and * represents a symbol indicating an optically active carbon atom) and can be used in chiral smectic mixtures.
摘要:
Novel compounds exhibiting in liquid crystal compositions a higher clearing point and a superior stability are provided which are trans-4-alkyloxymethyl-1-(4'-substituted biphenylyl-4)cyclohexanes expressed by the general formula (I): wherein R, and R 2 each represent an alkyl group of 1 to 8 carbon atoms and n represents 0 or 1.
