Liquid-crystalline compounds have the general formula (I): X(-Y-A-Y-M-Y-B)n, in which X is an aromatic or aliphatic ring system; n is an integer from 2 to 6; the Y symbols represent independently from each other a direct bond, -COO-, -OCO-, -O-, -CONH- or -CON(R)-, in which R = C1 to C4 alkyl; A is a spacer; M is a mesogene group; and B is a lateral chain. These compounds are particularly suitable in displays or for producing light-reflecting layers. |
