中文摘要	a monomer, 2,3,6,7,10,11-hexakispentyloxy triphenylene (hpt) possesses a triphenylene core as a discotic mesogen. polymers containing this discotic mesogen have been studied using wide-angle x-ray and electron diffraction. hpt is known to show a discotic liquid crystal phase, noted as d-ho (h for hexagonal bidimensional lattice, o for ordered molecular spacing in each column). in this paper, however, hpt liquid crystalline phases, heated up from the crystalline state and cooled down from the isotropic state, were characterized in the diameter dimensions. in addition. the diameters of the columns are close to a parameter of two separate crystals. a core orientation was, therefore, proposed in the mesophase obtained by heating the crystalline. in order to distinguish these differences, the d-ho phase was divided to include the d-hcd and d-hco phases. molecular modeling was performed to help our understanding of the orientation. the d-hcd and d-hco phases were used to characterize the phases of the discotic polymeric analogs by comparing their column diameters to those of the monomers.
