dc.description.abstract | Poly(2-fluoro-1,4-phenylenevinylene) (PFPV) and poly(1,4-phenylenevinylene) (PPV) were synthesized through the water-soluble precursor method. The polymers were characterized by UV-visible spectroscopy, and the light-emitting properties were studied. The absorption maxima of PPV and PFPV are at around 415 and 410 nm, respectively. The electroluminescent (EL) devices were fabricated with ITO and aluminum as positive and negative electrodes, respectively. The EL properties of these polymers were studied by EL spectra, current-voltage characteristics, light intensity-current characteristics, and Fowler-Nordheim plot. The I-V characteristics of the polymers showed typical diode characteristics, and the operating voltages of PPV and PFPV were 6 and 10 V, respectively. The photoluminescent spectra of these polymers were also obtained and similar to the EL spectra. The relative EL quantum efficiency of PFPV was 10 times higher than that of PPV. This result may be due to the smaller band offset between the aluminum and the LUMO of the PFPV as compared with that in PPV. | - |
