The calculation and analysis of molecular parameters (MPs) has been carried out for five series of triphenylene derivatives and crown ether derivatives (30 molecules) containing chiral or complexing centers. The values of the MP were used to predict possible occurrence of columnar and nematic mesomorphism in these series. Several representatives of these series were synthesized and their mesomorphic behavior was studied. A special attention was paid to enamine ketone derivatives of crown ether, in which the transition from the liquid-crystal state to the vitreous state with retention of the mesophase structure at the ambient temperature was observed.
