摘要
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。
Abstract
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 characterized 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).
