碩士 === 國立暨南國際大學 === 應用化學系 === 106 === Nine triazine-based compounds are reported to be successfully prepared through the unique substitution properity of 2,4,6-trichloro-1,3,5-triazine. All of them are divided into two categories; The first part is the derivatives of 2-diphenylamine-4,6-dichloro-1,3,5-triazine and two dichloro atoms are replaced by the same functional group. The second part is the derivatives of 2-diphenylamine-4-benzimidazole-6-chloro-1,3,5-triazine and one chloro atom is replaced by different functional groups, which are pyrazole, piperidine, phenoxazime or benzotriazole…etc. These functional groups make the triazine-based compounds have different π-conjugated and electron distribution and cause the UV-vis adsorption and emission variation. By theoretical calculation, we estimate the HOMO and LUMO energy differences of triazine-based compounds. In addition, these compounds have been characterized by NMR spectroscopy and mass spectrometery. The thermal stability of these compound were studied by the thermogravimetric analysis.
