ABSTRACT:
Disclosed herein are organic light emitting devices in which emitting layers (EL) comprise a suitable receiving compound according to Formulas I and II: ##STR1## wherein M is an ion of a divalent or trivalent metal atom, wherein n=3 when M is trivalent, and n=2 when M is divalent, wherein the metal atom is selected from the group consisting of aluminum, gallium, indium, and zinc, and wherein X, Y, and Z are each individually and independently C or N, such that at least two of X, Y and Z are N; and ##STR2## wherein R is alkyl, phenyl, substituted alkyl, substituted phenyl, trimethylsilyl, or substituted trimethylsilyl.
Also disclosed are OLED's utilizing device elements comprising the above compounds and display devices based on those OLED's.
