Embodiment 1
[0191] Compounds for organic photoelectric devices were synthesized according to the following reaction scheme 1.
[0192] [Reaction Scheme 1]
[0193]
[0194] The first step: the synthesis of intermediate product (B)
[0195] Under an argon atmosphere, 11.0 g (24.7 mmol) of compound A, 6.0 g (29.7 mmol) of 1-bromo-2-nitrobenzene, and 1 g (0.86 mmol) of tetrakis(triphenylphosphine) palladium and 200 ml of tetrahydrofuran ( THF) was mixed in a 500ml round bottom flask equipped with a thermometer, reflux condenser and stirrer, to which 250ml of 2M potassium carbonate was added. The resulting mixture was stirred at 75°C for 24 hours.
[0196] The reactant was cooled to complete the reaction, extracted with dichloromethane and washed with water. Next, the resulting reactant was treated with anhydrous magnesium sulfate to remove water therefrom, and then filtered to remove the organic solvent. The final residue was purified by silica gel chromatography using a mixed solvent...
Embodiment 2
[0207] Compounds for organic photoelectric devices were synthesized according to Reaction Scheme 2 below.
[0208] [Reaction Scheme 2]
[0209]
[0210] The first step: the synthesis of intermediate product (E)
[0211] Under an argon atmosphere, in a 500ml round bottom flask with a thermometer, a reflux condenser and a stirrer, 10.0g (22.5mmol) of compound D, 5.45g (27mmol) of 1-bromo-2-nitrobenzene and 1g (0.86 mmol) of tetrakis(triphenylphosphine)palladium was dissolved in 200 ml of tetrahydrofuran, and 50 ml of 20% tetratriethylammonium hydroxide was added thereto. The mixture was stirred at 75°C for 24 hours.
[0212] Next, the reactant was cooled to complete the reaction, and then extracted with dichloromethane and washed with water. Next, the resulting reactant was treated with anhydrous magnesium sulfate to remove water therefrom, and then filtered to remove the organic solvent. The final residue was purified by silica gel chromatography of a mixed solvent prepa...
Embodiment 3
[0224] By using the compound synthesized in Example 1 as a host, Ir(PPy) 3 Used as a dopant to make organic light-emitting diodes. Here, put 1000 thick ITO is used as the anode, while the 1500 Thick aluminum (Al) was used as the cathode.
[0225] Specifically, the method of manufacturing an organic light emitting diode includes making the sheet resistance 15 Ω / cm 2 The ITO glass substrate was cut into a size of 50 mm × 50 mm × 0.7 mm, and the substrate was ultrasonically cleaned in acetone, isopropanol and pure water for 15 minutes, and then cleaned with UV ozone for 30 minutes to prepare an anode.
[0226] at 650 x 10 -7 With a speed of 0.1 to 0.3nm / s under the vacuum degree of Pa, N, N'-two (1-naphthyl)-N, N'-diphenylbenzidine (NPB) (70nm) and 4,4', 4″-tris(N-carbazolyl)triphenylamine (TCTA) (10 nm) was deposited on the substrate to form 800 Thick hole transport layer (HTL).
[0227] Then, the compound synthesized according to Example 1 was deposited under the same...
