| titleOfInvention | Liquid-crystalline, 1-substituted piperidine-4-carboxylic acid esters |
| abstract | Liquid-crystalline, 1-substituted piperidine-4-carboxylic acid esters, process for their preparation, and their use in liquid-crystalline mixtures n The novel 1-substituted piperidine-4-carboxylic acid esters of the general formula (I) ##STR1## are liquid-crystalline and exhibit, in particular, S c or S c * phases. In this formula, R 1 or R 2 is a radical of the general formula (II) ##STR2## in which the rings are aromatic, heteroaromatic or optionally heteratom-containing cycloaliphatic molecular components, such as 1,4-phenylene, pyrimidine-2,5-diyl or trans-1,4-cyclohexylene, which are linked via a single bond (in the case where n and p=zero) or via functional groups Z 1 or Z 2 such as CO- or CH 2 -O, and in which k, n, m, p and q are zero or 1, where k+m+p is at least 1 and p=zero when m=zero. The other radical R 1 or R 2 is an optionally substituted straight-chain or branched alkyl group having 1 to 20 carbon atoms, X 1 denotes, S, phenylenoxy or CH 2 , and X 2 denotes O or phenylenoxy. |
