dc.description.abstractA novel supramolecular liquid crystal complex has been designed and formed from pure liquid crystalspara-azoxyanisole (PAA) and 4-hexylbenzoic acid (6BA). Thermal and microstructural properties offormed PAA/6BA binary liquid crystal complex system are investigated by differential scanning calo-rimeter (DSC), polarized optical microscopy (POM) and X-ray diffractometer (XRD). Fourier transformedinfrared spectroscopy (FTIR) is used to confirm the formation of hydrogen bond between the PAA and6BA molecules. The XRD results show that the molecular ordering of the hydrogen bonded PAA/6BAcomplex is arranged in the orthorhombic structure. The DSC and POM results clearly indicate that thePAA/6BA binary complex exhibits liquid crystalline properties due to the hydrogen bonds formed be-tween the PAA and 6BA molecules. The PAA/6BA complex shows the phase transition peaks indicatingCr/N/I and I/N/SmA/Cr phase sequence during continuous heating and cooling, respectively, byDSC. These phase sequences have also been confirmed by POM observations. Furthermore, the effect ofthe heating rate on the phase transition temperature values is investigated. As the heating rate increases,the phase transition temperature values increase as well. Moreover, the activation energies for the phasetransitions of the PAA/6BA liquid crystal complex are calculated by using Kissinger, Ozawa and Takhormethods. The calculated results clearly show that the phase transitions are regular.en_US
