摘要:

以咔唑和联苯为原料合成了2个含咔唑基团的新型β-二酮,并用1H NMR、13C NMR、MS、元素分析、热分析、紫外可见吸收光谱及荧光光谱等测试技术进行了表征。 2种β-二酮具有较高的热稳定性,5%失重温度(ΔT5%)分别为319和356 ℃,荧光发射位于蓝光区,最大发射峰为443和455 nm。

关键词: β-二酮, 咔唑, 联苯, 克莱森缩合

Abstract:

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.

Key words: β-diketones, carbazole, biphenyl, Claisen condensation
