Synthesis and specific features of mesomorphic behavior of new polysubstituted triphenylenes

Previously unknown 2,3,6,7,10,11-hexakis(dodecyloxy)triphenylene and -(tetradecyloxy)triphenylene were synthesized. The structures of the synthesized compounds were proved by elemental analysis and spectral methods. Polymesomorphism was found for the first time and studied for substances of the hexaalkoxytriphenylene homologic series, as well as liotropic mesomorphism in a series of organic solvents.

Discotic nickel bis(dithiolene) complexes - Synthesis, optoelectrochemical and mesomorphic properties

Fifteen neutral long-chain-substituted discotic nickel bis(1,2-diphenyl-1, 2-ethenedithiolene) complexes [Ni(dpedt)2], including thirteen new compounds, have been synthesized by new short and efficient synthetic pathways. Physical investigations show that these complexes are thermally stable, possess good electron-accepting properties, and absorb light strongly in the near-infrared spectral region. Electrochemical and optical properties of [Ni(dpedt)2] depend moderately on the functionalities attached to the phenyl rings of the complexes. Their LUMO and HOMO energy levels are in the range -4.7 to -5.0 and -5.7 to -6.0 eV, respectively. Two octa(n-alkoxy)- substituted complexes exhibit a columnar liquid crystalline phase with hexagonal symmetry. These highly soluble complexes are potential candidates for use as electron-accepting and electron-transporting materials for active layers in organic electronic applications, such as field-effect transistors or photovoltaic devices. Electrochemical and optical studies as well as multiphase transition behavior are reported for a series of new nickel bis(dithiolene) complexes. The effects of the nature and position of the functional groupsattached to the periphery of the complexes are investigated. X-ray diffraction measurements regarding the hexagonal columnar mesophase are reported. Copyright

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.
