preparation example 1

[0204] Synthesis of Compound 1

[0205]

[0206] Compound C (7.17g, 22.2mmol) and 4-bromo-N,N'-diphenylaniline (7.17g, 22.2mmol) were completely dissolved in 60ml of xylene, and sodium tert-butoxide (2.56g , 26.6 mmol), and the resulting mixture was stirred while increasing the temperature until the resulting mixture was refluxed. When the mixture started to reflux, bis(tri-tert-butylphosphine)palladium (0.11 g, 0.22 mmol) was slowly added dropwise thereto. After 12 hours, the reaction was terminated, the temperature was lowered to normal temperature, and the resulting product was concentrated under reduced pressure, followed by column purification to prepare 8.68 g of Compound 1.

preparation example 2

[0208] Synthesis of Compound 2

[0209]

[0210] 9.54 g of Compound 2 were prepared by reacting and purifying in the same manner as in Preparation Example 1, except that Compound C (7.17 g, 22.2 mmol) and (4'-bromo-N,N'-diphenyl) were used Biphenyl-4-amine (8.86 g, 22.2 mmol).

Abstract

This manual involves compounds and organic electronic devices containing it.

Description

technical field [0001] This application claims priority and benefit from Korean Patent Application No. 10-2015-0128575 filed with the Korean Intellectual Property Office on September 10, 2015, the entire contents of which are incorporated herein by reference. [0002] The present description relates to compounds and organic electronic devices comprising them. Background technique [0003] An organic electronic device means a device that requires charge exchange between an electrode and an organic material using holes and / or electrons. Organic electronic devices can be broadly classified into the following two categories according to their operating principles. First, an organic electronic device is a form of an electronic device in which excitons are formed in an organic material layer by photons flowing into the device from an external light source, the excitons are separated into electrons and holes, and the electrons and holes are each transferred to The different elect...
