Alkyl sp3C–H bonds of cycloalkanes and functional branch/linear alkanes have been successfully brominated with KBr using air or O2 as an oxidant at room temperature to 40 °C. The reactions are carried out in the presence of catalytic NaNO2 in 37% HCl (aq)/solvent under visible light, combining aerobic oxidations and photochemical radical processes. For various alkane substrates, CF3CH2OH, CHCl3, or CH2Cl2

A compound having a high glass transition temperature, high electric stability, and/or high luminescent efficiency, and an organic light-emitting device including an emitting layer including the compound, which is represented by Formula 1:
In Formula 1, A may be a moiety formed by fusing a substituted or unsubstituted indole group, as represented by Formula 1-1:
When the compound represented by Formula 1 is used as a material for an emitting layer, an organic light emitting device including the compound may exhibit decreased driving voltage and improved efficiency and lifespan, as compared to OLEDs containing compounds that are available in the related art.
An organic light-emitting device includes a first electrode and a second electrode facing the first electrode. An organic layer is disposed between the first electrode and the second electrode. The organic layer includes an emission layer, a first compound and a second compound.
