A 3-fluoropyridine of the formula (I) STR1 in which the symbols have the following meanings: R1 and R2, independently of one another, are, for example, H or straight-chain or branched alkyl, A1, A2, A3 and A4 are identical or different and are, for example, 1,4-phenylene, pyrazine-2,5-diyl or trans-1,4-cyclohexylene, M1, M2, M3 and M4 are identical or different and are, for example, --O-- or --CO--O--, R3, R4, R6 and R7, independently of one another are, for example, H or straight-chain or branched alkyl, M5 is for example, --O--CO-- or a single bond, k, l, m, n, o, p, q and r are zero or one, with the proviso that the sum k+m+p+r is less than 4 and greater than zero, can advantageously be employed as a component in ferroelectric liquid-crystal mixtures.
