LIGHT EMITTING ELEMENT AND AMINE COMPOUND FOR THE SAME
摘要:
A light emitting element of one or more embodiments includes a first electrode, a second electrode provided on the first electrode, and at least one functional layer provided between the first electrode and the second electrode, wherein the functional layer includes an amine compound including a spiro-bonded linker of two hydrocarbon rings and two amine groups connected with the linker. The light emitting element may have improved emission efficiency and element life.
synthesized from 3-methoxybenzaldehyde in 26 % yield over 9 steps and resolved via its bis-(S)-camphorsulfonates. The corresponding chiral spirobitetraline monophosphoramidite ligands have been prepared and their rhodium complexes were applied in the asymmetrichydrogenation of dehydroamino esters with good to excellent enantioselectivities (up to 99.3 % ee).
