Abstract
Tandem carbene phosphors such as those of Formula I can act as electron acceptors in tandem to increase the energy separation between the ground and excited state, which is higher than those found in analogous monometallic complexes. These compounds should find application as luminescent materials in organic light emitting diodes (OLEDs).
