| Abstract: | A series of liquid crystal compounds bearing different alkoxy chains and benzene ring as a rigid center have been prepared via alkyne cyclitrimerization. IR, 1H NMR, 13C NMR,MS were used to identify the structures of all these compounds. Differential scanning calorimetry (DSC) was used to investigate the liquid crystal properties of the serial compounds. The effects of the length of alkoxy chains on liquid crystal properties have been primarily probed. |
