[0131] Synthesis Example: Synthesis of Compound 10
[0132]
[0133] Synthesis of Intermediate C-2
[0134] 300ml of toluene was added to 28.6g (100mmol) of compound C-1, 9.8g (50mmol) of benzophenone hydrazone, 330mg (3mol%) of Pd(OAc) 2 and 7.3 g (75.0 mmol) of KOt-Bu, and then heated at 90° C. for 4 hours in a nitrogen atmosphere. The reaction mixture was cooled to room temperature, 100 ml of water was further added to the reaction mixture, and extracted twice with 500 ml of dichloromethane. The organic phase was dried, filtered, concentrated, and then separated by column chromatography to obtain 14.4 g of compound C-2 in the form of a yellow solid in a yield of 72%. The structure of compound C-2 was confirmed by high resolution mass spectrometry (HR-MS). (theoretical value: 400.0575, observed value: 400.0564)
[0135] Synthesis of Intermediate C-3
[0136] 100ml of toluene and 50ml of ethanol were added to 20.1g (50mmol) of compound C-2, 38.0g (200mmol) of pT...
Embodiment 1
[0171] By placing a Corning 15Ωcm 2 The ITO glass substrate was cut into a size of 50 mm × 50 mm × 0.7 mm, and the glass substrate was ultrasonically cleaned with isopropanol and pure water for 5 minutes, and then irradiated with UV light for 30 minutes and exposed to ozone for cleaning to prepare the anode. Then, the anode is loaded into the vacuum deposition equipment.
[0172] Subsequently, 2-TNATA (HIL material) was vacuum-deposited on the glass substrate to form a Thickness of HIL. Then, 4,4'-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (NPB) (a hole-transporting compound) was vacuum-deposited on the HIL to form a Thickness of HTL.
[0173] Then, a green fluorescent host (Alq3) and a green fluorescent dopant (C545T) were simultaneously deposited on the HTL at a weight ratio of 98:2 to form a thickness of EML.
[0174] Subsequently, compound 10 was deposited on the EML to form a thickness of ETL, and then deposit LiF (halogenated alkali metal) on the ETL to form...
Embodiment 2
[0177] An organic light-emitting device was fabricated by the same method as in Example 1, except that compound 17 was used instead of compound 10 to form an ETL.
[0178] The organic light-emitting device at 50mA / cm 2 It has a driving voltage of 6.17V at a current density of 8384cd / m 2 High brightness, (0.310,0.643) color coordinates and 16.77cd / A luminous efficiency.
