Abstract
Complexes and devices, such as organic light emitting devices and full color displays, including a compound of the formula: wherein: M is Pd2+, Ir+, Rh+, or Au3+; each of V1, V2, V3, and V4 is coordinated to M and is independently N, C, P, B, or Si; each of L1, L2, L3, and L4 is independently a substituted or unsubstituted aryl, cycloalkyl, cycloalkenyl, heterocyclyl, heteroaryl, carbene, or N-heterocyclic carbene; and Z is O, S, NR, CR2, SiR2, BR, PR, where each R is independently substituted or unsubstituted C1-C4 alkyl or substituted or unsubstituted aryl.
Claims14
A compound of General Formula I:
- wherein:
- M is Pd2+, Ir+, Rh+, or Au3+;
- each of V1, V2, V3, and V4 is coordinated to M and is independently N, C, P, B, or Si;
- each of L1, L2, L3, and L4 is independently a substituted or unsubstituted aryl, cycloalkyl, cycloalkenyl, heterocyclyl, heteroaryl, carbene, or N-heterocyclic carbene;
- wherein at least one of L1, L2, L3, and L4 comprises the N-heterocyclic carbene of a formula:
- that is bonded to M by way of the wavy line;
- and
- Z is O, S, NR, CR2, SiR2, BR, PR,
- where each R is independently substituted or unsubstituted C1-C4 alkyl or substituted or unsubstituted aryl.
