| 摘 要： | 以2-溴-9-乙基-9H-咔唑为原料,首先与联硼酸频那醇酯经宫浦硼基化反应制得相应的有机硼产物,再与溴代物发生传统的铃木偶联反应合成了3种新型的环金属配体(3a~3c);3a~3c依次与三氯化铱及传统辅助配体乙酰丙酮反应合成了3个新型含苯并唑类(苯并恶唑、苯并噻唑和苯并吡唑)环金属铱配合物(4a~4c),其结构经~1H NMR和MS(ESI或FAB)表征。并对其紫外和荧光光谱进行了研究。结果表明:4a~4c由于主配体的结构微调,可实现发光颜色由黄绿色到橙色的调控。

| Abstract: | Three novel cyclometalated ligands(3a~3c)were prepared by Miyaura borylation reaction and Suzuki coupling reaction from 2-bromo-9-ethyl-9H-carbazole.Three novel cyclometalated benzoxazole-based(benzoxazole, benzothiazole and indazole) iridium(Ⅲ) complexes(4a~4c) were synthesized by reaction of 3a~3c with iridium chloride and acetylacetone successively.The structures were characterized by 1H NMR and MS(ESI or FAB).The photophysical properties of 4a~4c were studied by UV-Vis absorption and emission spectra.The results showed that the phosphorescent emission of 4a~4c can be realized from yellow green to orange, which is mainly dependent on the main ligand structure. |
