Silanylamine-based compound, method of preparing the same and organic light emitting device including organic layer comprising the silanylamine-based compound

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.
