Since Chandrasekhar et al. have first discovered discotic liquid crystal (DLC) in 1977, DLC materials have been attracting attention due to their particular transport properties like electron or hole transfer etc. The objective of our study is to design the hydrogen-bonded complexes that show the DLC behavior and to cross-link the DLC material to maintain the structure at any temperature. Our strategy to obtain the complexes is to use hydrogen bonding between core unit and peripheral unit. At this study, core unit is Phloroglucinol (PG, H-bond donor) and peripheral unit is 11-(4-(pyridin-4-yl)phenoxy)undecyl acrylate (PPUA, H-bond acceptor). The existence of the hydrogen-bonded complexes was studied by FT-IR spectroscopy. The mesomorphic properties of PG/PPUA complexes were studied by DSC, POM and X-ray diffraction. The PG/PPUA complex exhibited columnar mesophase. |
