摘要: An OLED is disclosed whose emissive layer has a first host and an emitter, where the emitter is a phosphorescent metal complex or a delayed fluorescent emitter, where EHIT, the T1 triplet energy of the first host, is higher than EET, the T1 triplet energy of the emitter, where EET is at least 2.50 eV, where the LUMO energy of the first host is higher than the HOMO energy of the emitter, where the absolute value of the difference between the HOMO energy of the emitter and the LUMO energy of the first host is ΔE1, where a≤ΔE1−EET≤b; and where a≥0.05 eV, and b≤0.60 eV.

摘要: An OLED is disclosed where the OLED includes, sequentially: an anode; a hole transporting layer; an emissive region; an electron transporting layer; and a cathode; where the emissive region includes a compound S1; and a compound A1. The compound S1 is an organometallic sensitizer that transfers energy to the compound A1, and the compound A1 is an acceptor that is an emitter in the emissive region. The compound S1 has a vertical dipole ratio (VDR) value greater than or equal to 0.2; and the compound A1 has a VDR value less than or equal to 0.2.

摘要: Provided is a new composition of matter for phosphorescent emitters containing a chelating ligand including five or more fused carbocyclic or heterocyclic rings that form two bonds to a metal forming a 7-membered chelate. This fused ring structure provides added rigidity to the molecule for enhanced stability in an OLED device and improve photophysical properties.
