[0168] 1. Reagents and Test Methods

[0169] All solvents and reagents were obtained from commercial vendors, including Sigma-Aldrich, TCI, and Alfa Aesar, and were prepared in the highest available purity and / or when necessary, regenerated prior to use. Used in crystalline form. Anhydrous solvents were obtained from an internal purification / distribution system (hexane, toluene, and tetrahydrofuran) or purchased from Sigma-Aldrich. All experiments involving "water-sensitive compounds" were performed in "oven-dried" glassware under a nitrogen atmosphere or in a glove box. Reactions were monitored by analytical thin layer chromatography (TLC) on pre-coated glass plates (VWR 60F254) and visualized by UV light and / or potassium permanganate staining. Flash chromatography was performed on an ISCO COMBIFLASH system with GRACERESOLV columns. GC-mass spectroscopy (GC-MS) was performed on a HP 6890 series GC system with a "12m x 0.2mm x 0.55μΜ" DB-Ms column (coiled).

Abstract

The present disclosure provides a composition. In an embodiment, a composition is provided and comprises a Compound 1 shown below: For Compound 1, R1 through R24 are the same or different. R1 through R24 each is independently selected from the group consisting of hydrogen, unsubstituted hydrocarbyl, substituted hydrocarbyl, cyano, alkoxy, aryloxy, and NR'2. R' is hydrogen or hydrocarbyl; wherein two or more of adjacent R1 to R24 may optionally form one or more ring structures. The Component Z is selected from the group consisting Group Z-1, Group Z-2, Group Z-3, Group Z-4, Group Z-5, Group Z-6 and Group Z-7 shown below: For Compound 1, one or more hydrogen atoms may optionally be substituted with deuterium.

Description

[0001] References to related applications [0002] This application claims priority to US Provisional Patent Application No. 62 / 097,310, filed December 29, 2014, the entire contents of which are incorporated herein by reference. Background technique [0003] An OLED (Organic Light Emitting Diode) is a type of light emitting diode (LED) in which the electroluminescent layer is a film of an organic compound that emits light in response to an electric current. A typical OLED has a multilayer structure and typically includes an indium tin oxide (ITO) anode and a metal cathode. Sandwiched between the ITO anode and metal cathode are several organic layers such as hole injection layer (HIL), hole transport layer (HTL), emissive material layer (EML), electron transport layer (ETL) and electron injection layer ( EIL). [0004] Several properties required for such electroluminescent and charge-transporting compounds include high fluorescence quantum yield in the solid state, high mob...
