The present invention relates to compounds of the formula ##STR1## in which Y represents an organosilicon radical; R" represents a divalent radical which connects the radical Y to the benzene ring via a chain of at least three atoms; X represents a radical of the formula --COOH, --CN, --CHO, --NH.sub.2 or --OH, in which it is possible to block the hydroxyl group with a protecting group; Z represents the same or different substituents in the 2-, 3-, 5- or 6-position to the radical X, preferably hydrogen or halogen atoms; and p represents a value of 0 to 4; and the use of these and related compounds in the preparation of compounds having liquid-crystalline properties.
本发明涉及以下式子的化合物:##STR1## 其中Y代表有机硅基团;R"代表通过至少三个原子链将基团Y连接到苯环上的二价基团;X代表式子--COOH、--CN、--CHO、--NH.sub.2或--OH的基团,其中可以用保护基阻断羟基;Z代表在基团X的2-, 3-, 5-或6-位上相同或不同的取代基,优选为氢或卤素原子;p代表0到4的值;以及这些和相关化合物在制备具有液晶性质的化合物中的应用。
