| 英文摘要 | Dicyanovinyl-substituted compounds as electron transport materials are rarely studied, especially oligomers. a new series of fluorene or carbazole-based and dicyanovinyl-capped oligomers consisting of benzene or thiophene segments were synthesized using the stille coupling reaction and their physical properties were investigated. optical spectra show that the introduction of electron-accepting groups induces an intramolecular charge transfer, resulting in a shift of the absorption onset toward longer wavelengths. moreover, the optical spectra of their films show intermolecular interactions, leading to bathochromic shifts with respect to the spectra in solution. cyclic voltammetry indicates that they have suitable homo and lumo energy levels, and the oligomers containing thiophene segments show lower lumo levels. the x-ray crystallography of compound ftcn shows that the compound exhibits extended pi stacking of the molecules. thermal analysis reveals that they are thermally stable and no phase transition was observed at low temperatures. |
