An organic electroluminescent device comprising an anode, an electroluminescent region, and a cathode. The luminescent region comprises a light-emitting material of Formula I ##STR00001## wherein R.sub.1 is independently selected from the group consisting of a hydrogen, an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, an amino group, an alkyl amino group, and an aryl amino group; R.sub.2 is independently selected from the group consisting of hydrogen, a hetero atom, and an alkyl group; R.sub.3 is independently selected from the group consisting of hydrogen, an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, a halogen atom, and a cyano group; and, R.sub.4 is independently selected from the group consisting of hydrogen, an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, a halogen atom, and a cyano group.
