Abstract
Further X-ray powder diffractometer measurements have been made on compound II-9 of the columnar liquid crystal series hexaalkanoyloxytribenzocyclononene. For this compound the transition temperature between the solid and the columnar phase is 26°C. Data have been collected at several temperatures from 2°C to 52°C. We compare results obtained from II-9 with results published for II-10, 12, 13 and 15. Unlike these other compounds, in the mesophase the diffraction patterns show a large number of lines, with at least four high angle lines superposed on the broad hump arising from scattering by the disordered hydrocarbon side chains. This indicates a more highly ordered structure than for the other compounds in this series.
