Synthesis and Characterizations of a Rod-Like Liquid Crystal TBO16A
A rod-like liquid crystal (LC) N,N-(terephthalaldehyde) bis (4-n-hexadecyloxyaniline) (TBO16A) was synthesized and investigated by nuclear magnetic resonance (NMR), fourier transform infrared (FTIR), differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and ultraviolet-visible (UV-vis) spectrophotometry. The FTIR, 1H NMR and UV-vis absorption data confirmed the molecular structure of TBO16A. Our results demonstrated that the TBO16A can form enantiotropic smectic A phase.
