ABSTRACT:
Disclosed is an electroluminescent device comprising a light emitting layer comprising a boron complex wherein the boron is bonded to a nitrogen atom of a 6-membered heteroaromatic ring group and to a nitrogen atom of a 5-membered heteroaromatic ring group, provided that the 5- and 6-membered heteroaromatic ring groups are further connected by an imine group, and provided that the 5-membered heteroaromatic ring group contains at least one additional heteroatom that is divalent or trivalent, and a process or device employing the device.
