Two β-diketones with carbazole group were synthesized from carbazole and biphenyl. The β-diketones were characterized by 1H NMR, 13C NMR, MS, elemental analyses, thermoanalysis, UV-Vis absorption spectra and photoluminescence(PL) spectra. The β-diketones have high thermal stability, their 5% mass-reduction temperatures(ΔT5%) are 319℃ and 356℃, respectively. Their PL spectra lie in blue light zone with the maximum emission peaks of 443 nm and 455 nm. They are potential ligands for synthesizing metal ion complexes targeted for light-emitting materials.
