Abstract

AK-1NA and AK-2NA based on dibenzo-diazocine and anthracene moieties were designed and synthesized. Normalized UV-visible spectra of AK-1NA and AK-2NA in film state showed maximum absorption wavelength of 394 and 393 nm. PL spectra of AK-1NA and AK-2NA showed maximum emission wavelength of 429 and 444 nm. At a current density of 10 mA/cm2, OLED devices of AK-1NA and AK-2NA exhibited luminance efficiency of 2.39 and 1.50 cd/A, power efficiency of 1.01 and 0.81 lm/W. Also, OLED devices of AK-1NA and AK-2NA devices exhibited CIE(x, y ) of (0.16, 0.22) and (0.23, 0.42).

摘要

设计并合成了基于二苯并二氮杂䓬和蒽部分的AK-1NA和AK-2NA。AK-1NA和AK-2NA薄膜状态下的归一化紫外可见光谱显示最大吸收波长分别为394和393nm。AK-1NA和AK-2NA的荧光光谱显示最大发射波长分别为429和444nm。在电流密度为10mA/cm²时，AK-1NA和AK-2NA的有机发光二极管器件的发光效率分别为2.39和1.50cd/A，功率效率分别为1.01和0.81lm/W。此外，AK-1NA和AK-2NA器件的有机发光二极管器件的CIE(x,y)分别为(0.16,0.22)和(0.23,0.42)。
