| Popis: | 90 Several highly soluble azomethine derivations will be synthesis by condensation of aromatic diamine with aldehyde containing carbazole moieties. The macromolecules will be characterized by FT-IR, 1H-NM, 13C-NMR, Mass and GC-Mass. It will be showed that the presence of the highly alkyl pendant group enhance the solubility of macromolecules as well as promote characterization and process. The thermal stability of the macromolecules was evaluated by TGA-DTA study. The optical and electronic properties of the macromolecules are investigated by UV-Vis absorption spectroscopy. The results show that the macromolecule emit blue, green-blue light （λ＝350∼450）upon UV excitation. |
