Реферат: The invention relates to a process of preparing a discotic liquid crystalline compound by intramolecular oxidative cyclisation of a diaryl compound in an organic solvent in the presence of a strong acid, characterized in that an oxidative agent comprising a chrom(VI)oxide derivative is used, to discotic liquid crystalline compounds obtainable from said process, to liquid crystalline media, (co)polymers or polymer networks with columnar phases comprising said discotic liquid crystalline compounds, and to the use of said discotic liquid crystalline compounds, liquid crystalline media or liquid crystalline (co)polymers with columnar phases for liquid crystal displays, optical elements like polarizers, compensators or colour filters, chemical sensors, charge transport materials, optical storage media, nonlinear optics, decorative pigments, adhesive or synthetic resins with anisotropic mechanical properties.
