Liquid crystal materials have a number of ordinary uniqueness such as mechanical or electro-optical properties. New triazines derivatives compound was obtained starting from 1,3,5-triazine and1,3,5-trichlorobenzene. The synthesized compound consist of three-armed, one arm of phenol, and two armed of 2,4-bis(dodecyloxy)-6-ethynyl-1,3,5-triazine which built up from the reaction between 1,3,5-triazine and dodecan-1-ol. The substitution was achieved efficiently at appropriate temperatures under the argon atmosphere by cross-coupling. However, the two armed of 2,4-bis(dodecyloxy)-6-ethynyl-1,3,5-triazine on the periphery are considered for liquid crystal application. The target compound did not exhibit a transition phase in its pure state but, after ionic interaction with 4-DBA which already possesses a phase transition, it showed a phase transition and liquid crystal properties. The organic salts obtained after ionic interaction through hydrogen bonding were investigated for their liquid crystal properties by optical polarizing microscope (POM) and differential scanning calorimetry (DSC). The intermediate and final compounds were purified by column chromatography and confirmed their structures by spectroscopic techniques (mass spectrometry, 1H NMR, 13C NMR, and FT-IR,).
