ABSTRACT
FT-IR spectra were measured on a PerkinElmer spectrum One (B) spectrometer (PerkinElmer, Foster City, CA). 1H NMR spectra were measured using a Bruker ARX 600 (Bruker, Germany) high resolution NMR spectrometer. The optical textures were observed with a Leica DMRX POM (Leica, Germany) equipped with a Linkam THMSE-600 (Linkam, United Kingdom) cool and hot stage. The thermal properties were determined with a Netzsch DSC 204 (Netzsch, Hanau, Germany) equipped with a cooling system at a heating and cooling rates of 10°C/min in a nitrogen atmosphere. The mesophase structure was identified using a Bruker D8 Advance (Bruker, Germany) X-Ray Diffraction (XRD) measurement with a nickel-filtered Cu-Kα radiation.
