Beschreibung
Zusammenfassung:	The invention relates to chiral photoisomerizable compounds of formula (I) wherein X1, X2, X3, X4, X5 and X6 have the meanings given in claim 1 , to liquid crystalline mixtures and polymers containing them, and to the use of chiral photoisomerizable compounds, liquid crystalline mixtures and polymers containing them in optical and electrooptical devices like liquid crystal displays or projection systems, in optical elements like polarizers, retardation films, compensators, color filters or holographic elements, in liquid crystal pigments and colored films or coatings for decorative or security applications, cosmetic and pharmaceutical compositions, in nonlinear optics and optical information storage.
