The invention relates to a polymerised liquid crystal (LC) film comprising at least one photoisomerisable compound and having a pattern of regions with different retardation and/or different orientation of the LC material, to methods of preparing such a film, and to its use as alignment layer, optical retardation film or optical waveguide in liquid crystal displays or other optical or electrooptical components or devices, or for decorative or security applications.

Polymerised liquid crystal film with retardation or orientation pattern

The invention relates to new polymerisable mesogenic or liquid crystalline compounds comprising a laterally substituted cinnamate group, to polymerisable mesogenic or liquid crystalline mixtures and anisotropic polymers prepared thereof, and to the use of the new compounds and the mixtures and polymers prepared thereof in optical and electrooptical devices, adhesives, synthetic resins with anisotropic mechanical properties, cosmetics, diagnostics, liquid crystal pigments, decorative and security applications, nonlinear optics, optical information storage, electronic devices like organic field effect transistors (FET or OFET), electroluminescent devices, or as chiral dopants.

Polymerisable cinnamates with lateral substitution

The invention relates to chiral photoisomerizable compounds of formula (I) wherein X, X, X, X, Xand Xhave the meanings given in claim, 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.

Chiral photoisomerizable compounds

The invention relates to a polymerizable liquid crystal material containing at least one polymerizable surface-active compound, its use for the preparation of anisotropic polymer films, and the use of the liquid crystal material and the polymer films in optical and electrooptical devices, and for decorative and security applications.

Polymerizable liquid crystal material

Described herein are compounds of formula Iwherein M, Mand Mhave the meanings recited in the disclosure, liquid crystalline mixtures and polymers containing them, and the use of the compounds of formula I, the liquid crystalline mixtures and the polymers containing them in optical and electrooptical devices like liquid crystal displays or projection systems, patterned films and optical elements like polarizers, retardation films, compensators, color filters, holographic elements or polarization beam splitters, for photoswitching, in anisotropic membranes for the permeation of gases or fluids, adhesives, synthetic resins with anisotropic mechanical properties, cosmetic or pharmaceutical compositions, UV absorbers and sunscreens, diagnostics or liquid crystal pigments, for decorative and security applications, in nonlinear optics, optical information storage or as dopants.
