Abstract The molecular design of chiral discotic mesogens is considered. Designing of new chiral discotic mesogens, the derivatives of polysubstituted benzene and triphenylene, with asymmetric atom of carbon was carried out. The prognosis of the general and chiral types of mesomorphism was carried out. Five representatives of a new series of triphenylene derivatives were synthesized and studied. Good correlation of the prognosis results of columnar and nematic mesomorphism with experimental data was established. All synthesized anilides of triphenylene with abietic, lipoic, dehydrocholic and tartaric acids along with columnar phase form mesophase with columnar helical alignment. In this case, the results of experiment adjust with the prognosis in ratio of 60 %. We found out that the presence of some chiral centres in one substitute with several polar groups under the maximum symmetry breakdown of a molecule is favourable for chiral mesomorphic properties.
