| 摘 要： | The novel fluorinated distyrylarylene, 4,4＇-bis（2,2-di（4-fluorophenyl）vinyl）biphenyl （DFPVBi）, was synthesized and fully characterized. The structure was confirmed with IR, 1↑H NMR, 13↑C NMR, 19↑F NMR and MS analyses. Its electronic and photoluminescence properties were investigated by UV-Vis absorption, cyclic voltammetry and fluorescence spectroscopy. The energy levels of the highest occupied molecular orbital （HOMO） and the lowest unoccupied molecular orbital （LUMO） are --5.77 and --2.75 eV, respectively.

The device exhibits a pure blue emission peaked at 454 nm, which indicates a maximum luminance of 5872 cd/m

| Abstract: | The novel fluorinated distyrylarylene, 4,4′‐bis(2,2‐di(4‐fluorophenyl)vinyl)biphenyl (DFPVBi), was synthesized and fully characterized. The structure was confirmed with IR, 1H NMR, 13C NMR, 19F NMR and MS analyses. Its electronic and photoluminescence properties were investigated by UV‐Vis absorption, cyclic voltammetry and fluorescence spectroscopy. The energy levels of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) are ?5.77 and ?2.75 eV, respectively. The electroluminescence properties of the organic light‐emitting diode fabricated by DFPVBi were also studied. The device exhibits a pure blue emission peaked at 454 nm, which indicates a maximum luminance of 5872 cd/m2 at 14.2 V and a maximum current efficiency of 2.82 cd/A at 10V, respectively. |
