We synthesized spirobifluorene and carbazole derivatives such as 5Ph-ECz-5Ph, Fr-ECz-Fr, 5Ph-SF-5Ph, and Fr-SF-Fr, through Diels–Alder reaction. The molecular structure was confirmed by nuclear magnetic resonance (NMR), elemental analysis (EA), UV–Visible, PL spectroscopies. Fr-ECz-Fr exhibited sky blue PL emission at 481nm and 5Ph-SF-5Ph exhibited ultra-violet PL emission at 374nm in CHCl3 solution, but 5Ph-ECz-5Ph and Fr-SF-Fr showed PL spectra at around 390 and 467, respectively. PL spectra at around 390 and 467, respectively. In non-doped device, 5Ph-ECz-5Ph and Fr-SF-Fr as emitting material showed 1.6 cd/A and 1.7 cd/A, respectively. |
