This thesis entitled “Triazine-Based New Macromolecules: Synthesis,
Characterization, and Properties" presents the synthesis and characterization
of four series of compounds. The synthesis protocols were carried out starting
from cyanuric chloride as the starting material. Cyanuric chloride has a wide
application in chemical industries, agriculture, polymer, dye and leather and it is
commercially cheap. In this study (2-chloro-4,6-bis((2-ethylhexyl)oxy)-1,3,5-
triazine) and 2-chloro-4,6-bis((3,7-dimethyloct-6-en-1-yl)oxy)-1,3,5-triazine
were used as intermediate compounds which were prepared from 2,4,6-
trichloro-1,3,5-triazine and used further in substitution reactions. Triazine
derivatives were successfully designed and synthesized. The synthesized
compounds were characterized by differential scanning calorimetry (DSC),
polarizing optical microscopy (POM) and confirmed by 1H NMR, 13C NMR mass
spectra, and FT-IR.
Equimolar mixtures of all synthesized compounds with the complementary 4-
dodecyloxybenzoic acid, which already possessed liquid crystal property,
resulted in the organic salts. The organic salts were confirmed by spectroscopic
methods (1H NMR, 13C NMR FT-IR and Mass spectrometry), and investigated for
their phase transition changes by differential scanning calorimetry (DSC) and
polarized optical microscope (POM).
