Abstract
The orientation of a thermotropic LC volume is achieved by means of thermotropic LC molecules firmly bonded chemically to a matrix. The orientation takes place due to the physical and chemical properties of the LC volume, chemically bonded to the matrix on the disordered LC volume. Hydrocarbon polymers or organosilanes are used as the matrix, to the functional groups of which the thermotropic liquid crystal molecules, which also have functional groups suitable for bonding to the matrix, are chemically linked. The chemically linked thermotropic LC may be a nematic, cholesterinic, discotic or smectic LC, with which nematic, cholesterinic, discotic or smectic LC volumes can be oriented. The matrix is chemically bonded covalently to the substrate surface and may be colored due to additional coupling of reactive dyes.
