摘要:
The invention relates to fluorinated aromatics of the formula (I) where X is CH2, C═O, CF2, O or S, Y is H or F, with the proviso that Y has to be F when X is CH2, and where the other parameters are as defined in claim 1, and also to their use in liquid-crystal mixtures, and also to liquid-crystal mixtures comprising these compounds and to liquid-crystal displays comprising these mixtures.
