摘要:
Chiral benzene derivatives of formula I ##STR1## in which R.sup.1*, R.sup.2*, X.sup.1, X.sup.2, A.sup.1, A.sup.2, Z.sup.1, Z.sup.2, L.sup.1, L.sup.2, L.sup.3, m, n and k are as defined in claim 1, and their use as chiral dopes in liquid-crystalline media, particularly for electrooptical displays, and to electrooptical displays containing such media.
