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.
