Abstract A new series of 1,3,5-triazine derivatives containing quinoline and substituted amines were synthesized and characterized to explore their thermal stability and electrical properties. The synthesized compounds were obtained through a nucleophilic substitution reaction on the chlorinated triazine core using quinoline and various substituted amines as nucleophiles. The purity and structure of the products were confirmed by IR, UV-Visible, ¹H NMR, ¹³C NMR, and elemental analyses. The thermogravimetric analysis (TGA) and differential thermal analysis (DTA) revealed multistep decomposition patterns, indicating high thermal stability due to the presence of aromatic and heterocyclic frameworks. The onset and peak decomposition temperatures varied with the nature of the substituents, suggesting that electron-donating groups enhanced stability compared to electron-withdrawing ones. The electrical conductivity of the triazine derivatives was measured in the solid state using the two-probe method. Results showed that conductivity increased with temperature, confirming semiconducting behavior. Substituents with extended conjugation and higher electron density improved charge transport. Overall, the study establishes that quinoline-based 1,3,5-triazine derivatives exhibit good thermal resistance and moderate semiconducting properties, making them promising materials for potential applications in electronic and optoelectronic devices.
