Embodiment 1

[0097] Using the mixture of compound 2 synthesized in Synthesis Example 1 and sodium quinoline phenolate (NaQ) (1:1 by weight) as an electron transport layer material to fabricate an organic light-emitting device with the following structure: m-MTDATA (750 ) / α-NPD(150 ) / GBH02: GBD32 (3%) (300 ) / ETL (200 ) / LiF(10 ) / Al(3000 ).

[0098] 15Ω / cm 2 ITO glass substrate (Corning, 1200 ) was cut into pieces with a size of 50 mm×50 mm×0.7 mm, followed by ultrasonic cleaning in isopropanol and pure water for 5 minutes each and UV / ozone cleaning for 30 minutes to form an anode. Then vacuum deposit a thickness of 750 on the anode The m-MTDATA to form a hole injection layer, vacuum deposited on the hole injection layer to a thickness of 150 α-NPD to form a hole transport layer. Then vacuum-deposit a thickness of 300 on the hole transport layer GBH02 (Gracel Co., Ltd.) as a blue fluorescent host and GBD32 (Gracel Co., Ltd.) as a dopant (97:3 by weight ratio) were used to ...
