为提高有机电致发光材料热稳定性和发光效率,设计合成了新型萘基蒽类蓝光材料。以9-溴-10-(2-萘基)蒽为原料,分别同4-(1-萘基)苯硼酸和4-(2-萘基)苯硼酸在四(三苯基膦)钯催化下进行 Suzuki 偶联,合成10-(2-萘基)-9-(4-(1-萘基)苯基)蒽(NPNA-1)和10-(2-萘基)-9-(4-(2-萘基)苯基)蒽(NPNA-2)。采用红外、核磁对其结构进行表征,通过TG、DSC 分析对其热稳定性进行研究,采用紫外和荧光光谱对其光谱性能进行表征。在波长378 nm 波长光激发下,二者均显现出了强发光性能,NAPA-1的λmax 为424 nm,NAPA-2的λmax 为428 nm,均为优秀的蓝光材料。
9-(4-(naphthalen-1-yl )phenyl )-10-(naphthalen-2-yl )anthracene (NAPA-1 ) and 9-(naphthalen-2-yl)-10-(4-(naphthalen-2-yl)phenyl)anthracene(NAPA-2)are synthesized starting from 9-bromo-10-(naphthalen-2-yl)anthracene,4-(naphthalene-1-yl)phenylboronic acid and 4-(naphthalen-2-yl)phenylboronic acid by Suzuki coupling reaction.Structures of the target compounds are character-ized by IR,NMR.Results of TG and DSC analysis show the compounds have good thermal stability. The PL spectra of NAPA-1 and NAPA-2 in solution were found to exhibit excellent blue emission with the peak maxima at λmax = 424 nm,428 nm respectively.NAPA-1 and NAPA-2 have excellent light emitting performance and could be used as materials for organic light emitting diodes (OLEDs).
