synthesis of phenoxathiinderivatives. A range of 1,2-dihaloarenes or 1-halo-2-nitroarenes reacted with 2-sulfanylphenol to give the desired products in good-to-excellent yields. It is intriguing that 1-halo-2-nitroarenes containing electron-donating groups worked well as substrates in this reaction. A simple and efficient method was developed for the synthesis of phenoxathiinderivatives. A range of
An organic light-emitting device comprises: a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode , the organic layer comprising an emission layer and a hole transport region, wherein the hole transport region is between the first electrode and the emission layer, and the hole transport region comprises a first compound represented by Formula 1 and a second compound represented by Formula 2:
