Abstract
1,3,5-Triazine compounds having diacetylenic groups and their charge transfer complexes with 2,4,7-trinitrofluoren-9-one (TNF) were prepared. The morphological changes were studied by differential scanning calorimetry (DSC), polarizing optical microscopy (POM), and X-ray diffraction (XRD) measurement. Although the 1,3,5-triazine compounds did not exhibit a mesophase, the charge transfer (CT) complexes with various mole ratios of TNF assembled into liquid crystalline phases. The CT complexes were UV-irradiated in the liquid crystalline (LC) state to yield oligomers.
