In this study, we designed and synthesized two blue fluorescence materials using 7,7-dimethyl-9-(10-phenylanthracen-9-yl)-7H-benzo[b]fluoreno[3,4-d]thiophene substituted anthracene derivatives. To characterize their electroluminescent properties, we fabricated the OLED devices using these two emitting materials. Particularly, a device using 7,7-dimethyl-9-(10-phenylanthracen-9-yl)-7Hbenzo[ b]fluoreno[3,4-d]thiophene showed maximum values of luminous efficiency, power efficiency, and external quantum efficiency of 2.42 cd/A, 1.48 lm/W, 3.08% at 20 mA/cm2, respectively with CIE () coordinates of (0.15, 0.09) at 8.0 V.
在本研究中,我们使用7,7-二甲基-9-(10-苯基蒽-9-基)-7H-苯并[b]芴并[3,4-d]噻吩取代的蒽衍生物设计并合成了两种蓝色荧光材料。为了表征它们的电致发光性能,我们使用这两种发光材料制备了有机发光二极管(OLED)器件。特别地,使用7,7-二甲基-9-(10-苯基蒽-9-基)-7H-苯并[b]芴并[3,4-d]噻吩的器件在20 mA/cm² 时的发光效率、功率效率和外量子效率的最大值分别为2.42 cd/A、1.48 lm/W、3.08%,在8.0 V时的CIE()坐标为(0.15, 0.09)。
