Triazine-based new macromolecules: Synthesis, characterization and properties

Abstract

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).
