摘要
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 and 1,3,5-trichlorobenzene. The synthesized compound consists of three-armed, one arm of phenol and two armed of 2,4-bis-(dode-cyloxy)-6-ethynyltriazine that built up via reaction of triazine with dodecan-1-ol. The substitution was achieved efficiently at appropriate temperature under the argon atmosphere by cross coupling. However, the two armed of 2,4bis(dodecyloxy)ethynyltriazine 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 possess a phase transition, it showed a phase transition and liquid crystal properties. We study the liquid crystal properties of obtained organic salts after ionic interaction through hydrogen bonding via methods of OPM "optical polarizing microscope" and DSC "differential calorimetric scanning). After purification with column chromatography then confirmed their structures by analysis of spectroscopy (MS, NMR, and FT-IR).
