New six-armed compounds consist of benzene ring as a central core substituted with aromatic ring and three rod-like armed of 2-chloro-4,6-bis(dodecyloxy)-1,3,5-triazine as the peripheral arms unit which were obtained by sequential nucleophilic substitution of chlorine atoms in cyanuric chloride. The substitution took place at the acetylenic periphery on the central benzene ring by cross-coupling. Equimolar mixtures of the six-armed compounds based on the benzene core with the complementary 4-dodecyloxybenzoic acid, which already possessed liquid crystal property, resulting in the organic salt. The organic salts and structures were investigated by differential scanning calorimetry (DSC) and confirmed by spectroscopic methods (H-1-NMR, C-13-NMR, Mass spectrometry, and FT-IR).
