Embodiment 1

[0173] The corning's 15Ω / cm 2 (1,200 Ȧ) ITO glass substrates were cut into pieces of 50 mm×50 mm×0.7 mm in size, cleaned ultrasonically with isopropanol for 5 minutes, ultrasonically cleaned with deionized water for 5 minutes, and cleaned with UV ozone for 30 minutes. Then, this glass substrate was installed in a vacuum deposition apparatus.

[0174] Compound 9 was vacuum deposited on the substrate to form a HIL with a thickness of 600 Ȧ. 4,4'-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (NPB) was vacuum deposited on the HIL to form the HTL with a thickness of 300 Ȧ.

[0175] IDE215 (a blue fluorescent host obtained from Idemitsu Co.) and IDE118 (a blue fluorescent dopant obtained from Idemitsu Co.) (98:2, w / w) were vacuum-deposited on the HTL to form a 300 Å-thick EML.

[0176] Then, Alq 3 Vacuum deposited on the EML to form an ETL with a thickness of 300 Ȧ, LiF was vacuum deposited on the ETL to form an EIL with a thickness of 10 Ȧ, Al was vacuum deposited on the EIL to a t...

Embodiment 2

[0178] An organic light emitting device was prepared as in Example 1, except that Compound 43 was used instead of Compound 9 when forming the HIL.

Embodiment 3

[0180] An organic light emitting device was prepared as in Example 1, except that Compound 44 was used instead of Compound 9 when forming the HIL.

Abstract

Silanylamine-based compounds represented by Formula 1 are provided. Methods of preparing the compounds and organic light emitting devices including organic layers comprising the silanylamine-based compounds are also provided. The silanylamine-based compounds have excellent electrical stability and electron transporting capabilities. Thus, the silanylamine-based compounds may be effectively used for red, green, blue, and white fluorescent and phosphorescent materials used to form hole injection layers, hole transport layers, and emissive layers in organic light emitting devices. Organic light emitting devices using these compounds have high efficiency, low driving voltages, high luminance and long lifetimes.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2006-0110187 filed with the Korean Intellectual Property Office on Nov. 8, 2006, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a silylamine-based compound, a preparation method thereof, and an organic light emitting device including an organic layer including the silylamine-based compound. Background technique [0004] Organic light-emitting devices (OLEDs) are self-emitting devices with wide viewing angles, excellent contrast ratio, and fast response. Organic light emitting devices have low operating voltage and fast response time, and can realize multi-color images. Therefore, organic light emitting devices are being extensively studied. [0005] A typical organic light emitting device has an anode / emissive layer / cathode structure. Organic light emitting devices can ...
