In this study, two blue fluorescence materials using phenylanthracene-substituted fluorene derivatives were synthesized and characterized for organic light-emitting diodes (OLEDs). To study their electroluminescent properties, OLED devices were fabricated using these two materials as emissive layer (EML). A device using 7,7-diphenyl-9-(10-phenylanthracen-9-yl)-7H-benzo[b]fluoreno[3,4-d]thiophene in emitting layer showed the highest value of EQE value which is 3.51%. It also showed the luminance efficiency of 3.22 cd/A and power efficiency of 2.89 lm/W with the CIE coordinates (0.15, 0.09).
在本研究中，合成了两种使用苯基蒽取代芴衍生物的蓝色荧光材料，并对其用于有机发光二极管（OLED）进行了表征。为了研究它们的电致发光特性，使用这两种材料作为发光层（EML）制作了OLED器件。在发光层中使用7,7-二苯基-9-(10-苯基蒽-9-基)-7H-苯并[b]芴并[3,4-d]噻吩的器件显示出最高的外量子效率（EQE）值，为3.51%。它还显示出3.22 cd/A的发光效率和2.89 lm/W的功率效率，色坐标为（0.15, 0.09）。
