摘要：
A compound having a metal coordination complex structure, where the compound is capable of functioning as a phosphorescent emitter in an organic light emitting device at room temperature is disclosed. The compound has a first ligand coordinated to a metal. The free-state of the first ligand has a first triplet energy T1 of EL at 77K, while the compound has a first triplet energy T1 of E at 77K, and the difference in energy (ΔE) between E and EL is ≤250 meV. The compound has a triplet emission spectrum with a FWHM value of no more than 45 nm. Organic light emitting devices, consumer products, and formulations containing the compounds are also disclosed.
