Abstract:
A novel bifunctional blue-light material, 9-(pyren-1-yl)-9H-carbazole (CzPy), has been syn-thesized and its structure is identified by electron ionization mass spectrometry, 1H NMR, and element analysis. The absorption, photoluminescence spectra and thermal properties were studied, results showedthat CzPy was stable under ambient conditions with a blue-light emission (461 nm).Additionally, its electroluminescence properties were characterized with four different devices. Results indicated a maximum luminous efficiency reached 1.56 cd/A and maximum luminance up to 3526 cd/m2 at 10 V with commission international De L'Eclairage coordinates of (0.20, 0.24) when it was used as emitter. Furthermore, CzPy also indicated hole-transporting ability.

摘要:
合成了一种新颖的具有空穴传输性能的咔唑芘衍生物,其化学结构使用电子电离质谱、氢核磁共振、元素分析鉴定. 系统的研究了该化合物的吸收性质、光致发光性质和热稳定性质,结果发现该化合物在室温下表现出稳定的蓝光发射,发光波长位于461 nm处;并且在常温下表现出好的热稳定性. 为了更进一步研究其发光和空穴传输性能,设计了四种不同结构的电致发光器件,系统地研究了它的发光性能和电荷传输性能,结果发现,最大蓝光发光亮度达到3526 cd/m2,其色坐标是(0.20, 0.24),其发光效率达到1.56 cd/A (10 V
