A compound comprising a first ligand selected from Formula I,
and Formula II,
is disclosed. In these structures, Y1 to Y12 and Z3 and Z4 are independently CR or N; where each R, R′, R″, RF, and RG is hydrogen or a substituent, where at least one dashed arc represents Rs joined into a 5-membered or 6-membered carbocyclic or heterocyclic ring; where the first ligand is complexed to a metal M; where ring G is a fused ring structure comprising five or more fused heterocyclic or carbocyclic rings, of which at least one ring is of Formula III
where the fused heterocyclic or carbocyclic rings of Ring G are 5- or 6-membered; where Y is selected from BR′, NR′, PR′, O, S, Se, C═O, S═O, SO2, CR′R″, SiR′R″, and GeR′R″. Organic light emitting devices and consumer products containing the compounds are also disclosed.
