Provided is an organic light-emitting device capable of outputting light with high efficiency and high luminance. The organic light-emitting device includes an anode, a cathode, an emission layer placed between the anode and the cathode, and an organic compound layer placed between the anode and the emission layer, in which the organic compound layer contains the following compound A and compound B: [Compound A] an organic compound free of a nitrogen atom and a metal atom, the compound having SP 2 carbon atoms and SP 3 carbon atoms, and having a ratio of the number of the SP 3 carbon atoms to the number of the SP 2 carbon atoms of 40% or more; and [Compound B] a compound having a tertiary amine structure.
Abstract:
This invention relates to fluorinating agents and, more particularly, to chiral non-racemic fluorinating agents useful for enantioselective fluorination, as well as to their synthesis and use and other subject matter. The fluorinating agents are based on a substituted 1,4-diazabicyclo[2.2.2]octane (DABCO) skeleton and provide electrophillic fluorine enantioselectively.
