Abstract
An organic light emitting device is provided. The device includes an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer includes material having the structure: M is a metal having an atomic weight greater than 40, m is at least 1, n is at least zero, R″ is H or any substituent, X is an ancillary ligand, and A is selected from the group consisting of aryl and heteroaryl rings, and B is an aryl ring. A material including the photoactive ligand of the above material is also provided.
