제목 Synthesis and properties of PFVs by introduction of carbazole units as pendants
초록 Novel electroluminescent(EL) copolymers containing carbazole units, poly[9-(6-(N-carbazolyl)-hexyl)-9-(2-ethylhexyl)-2,7-fluorenevinylene]-co-poly[9,9-bis(2-ethylhexyl)-2,7-fluorenevinylene] (CzPFVs), have been synthesized by the GILCH polymerization. All CzPFVs exhibited absorption spectra with maximum peaks at around 417 nm. In the PL emission spectra of CzPFVs, maximum peaks around 463 nm and shoulder peaks around 490500 nm were exhibited. By adjusting the feed ratios of carbazole units in the CzPFVs, it is possible to have the higher current density and brightness, and the lower turn-on voltage due to increasing hole injection ability. The maximum luminescence of CzPFV9 was 2003 cd/m2 at 7 V. Particularly, the 1:1 mixture of CzPFV10 and PVK didn’t show any change in PL spectra even after annealing the thin film at 80 °C up to 60 min.
