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.
