Abstract
A series of new liquid crystals LCs and liquid crystalline thermosets LCTs were prepared from wholly aromatic mesogens containing 26naphthalene diol 26ND 27naphthalene diol 27ND hydroquinone HQ and biphenol BP Crosslinked LCTs were obtained by crosslinking their citraconimide reactive end groups under a range of heat treatment conditions The LCs and crosslinked LCTs were characterized by Fourier transform infrared FTIR spectroscopy 1H nuclear magnetic resonance NMR differential scanning calorimetry DSC thermogravimetric analysis TGA polarizing optical microscopy POM with a hot stage and wide angle Xray diffraction WAXD All LCs were thermotropic and formed a Schlieren nematic texture The LCTs did not exhibit a liquid crystalline mesophase which indicates that they are nonmesogenic phases
