    • Compound 7 was quenched to room temperature from its LC state at 199°C and subjected to X-ray analysis. In the small angle region, two peaks corresponding to d spacings of 44.8 and 25.9 Å appeared. They are in the ratio of 1:1/√3, which is in good agreement with a hexagonal lattice.

    • Polymerization of compound 7 was performed by irradiation with UV light (a high-pressure mercury arc lamp, 100 W) for 10 h in the LC state (205°C). In compound 7, each 1,3,5-triazine ring had three diacetylenic groups and about 41% of them were found to participate in the polymerization, when measured by IR spectroscopy. In the X-ray analysis, the polymer showed two peaks corresponding to d spacings of 39.8 and 27.5 Å, indicating that polymerization accompanied slight change of the monomeric alignments. One of likely arrangements of the polymer chains is a rectangular columnar phase when two reflections in X-ray diffractogram could be indexed as (100) and (010).
