Polysubstituted triphenylenes with active groups. Molecular parameters, synthesis, structure, and mesomorphism

Molecular parameters of hexaalkoxytriphenylenes with different substituents on the periphery of the triphenylene nucleus of known and hypothetical structures are calculated. The probability of a discophase for compounds of this series is estimated from molecular parameters. Several compounds of this series having polar groups (NO2, NH2) in the 1 position of the triphenylene nucleus have been synthesized. The compounds synthesized were investigated by thermopolarizing microscopy and X-ray diffraction analysis. The data on the mesomorphism of the new compounds are in good agreement with our prediction that alkoxytriphenylenes with polar groups have a discophase. It is established that introduction of an electron-accepting group at position 1 of the triphenylene nucleus expands the temperature range of existence of the discophase to room temperature. On the contrary, introduction of an electron-donating group narrows this interval. Compounds of this series presumably have a hexagonal columnar structure. 1998 Plenum Publishing Corporation.

Synthesis and study of heptasubstituted triphenylenes with chiral fragments and predictable type of mesomorphism

The forecasting of columnar and chiral mesomorphism was done for the new series of triphenylene derivatives. The mesomorphic properties of the two heptasubstituted triphenylenes containing chiral fragments were studied. The prediction results agreed well with the experimental data. Anilides of 1-amino-2,3,6,7,10,11-hexa(heptyloxy)triphenylene with abietic and dihydrocholic acids were found to exhibit the enantiotropic columnar dimesomorphism and to display the chiral columnar mesophases in the low-temperature range. The anilides obtained possess a lower thermal stability and extended interval of the mesophase existence than the initial amine.

Synthesis and investigation of polysubstituted triphenylenes with a predictable type of mesomorphism

This paper reports on synthesis and investigation of columnar mesophases of the new members of the homologous series of nitro and amino derivatives of hexaalkoxytriphenylenes, whose mesomorphism was predicted earlier. The forecast is in good agreement with the experimental data. The effect of the introduction of the donor and acceptor groups into the central fragment of triphenylene on the phase transition temperature, texture, and range of existence of columnar mesophases is examined. The predicting ability of the molecular parameters suggested previously for the series under analysis is discussed. It is found that introduction of a nitro group, which is a strong electron acceptor, into the central fragment of triphenylene lowers the melting temperature of the compound versus its analog and does not promote columnar mesomorphism in the lower nonmesomorphous homologs. At the same time, this slightly expands the range of existence of the mesophase in higher homologs.
