LIGHT-EMITTING DEVICE INCLUDING AMINE-CONTAINING COMPOUND, ELECTRONIC APPARATUS INCLUDING LIGHT-EMITTING DEVICE, AND AMINE-CONTAINING COMPOUND
摘要:
A light-emitting device including a first electrode, a second electrode facing the first electrode, and an interlayer between the first electrode and the second electrode and including an amine-containing compound represented by Formula 1, an electronic apparatus including the light-emitting device, and the amine-containing compound represented by Formula 1 are provided.
A general method for the synthesis of five‐membered and six‐membered selenaheterocycles through Ag‐catalyzed C−Se bond‐forming reaction is reported. This reaction proceeds via intramolecular cyclization of arylboronic acids with selenium powder. Preliminary mechanism studies demonstrate that this transformation involves a selenium‐centred radical intermediate.

the reductive elimination process prior to protonolysis, affording the [4 + 2] annulated products instead of the simple 1,4-addition product. Seven-membered rings were obtained when disubstituted cyclopropenones were employed. Bridged cycles were isolated from the coupling of 2-biphenylboronic acid with benzoquinones as a result of 2-fold Michaeladditions. The substrate scopes were found to be broad

approach to reduce the singlet-triplet energy gap in fully conjugatedpolymers, using a donor-orthogonal acceptor motif to spatially separate electron and hole wave functions. This new generation of conjugatedpolymers allows for a greatly reduced exchange energy, enhancing triplet formation and enabling thermallyactivateddelayedfluorescence. We find that the mechanisms of both processes are driven
