For example, the phosphorescent dopant compound may be comprised of platinum octaethylporphine (PtOEP), which is a compound having the chemical structure with the formula:

An organic light emitting device comprising a heterostructure for producing electro-luminescence. The heterostructure has a charge carrier layer that includes a compound having molecules having at least one electron transporting moiety that is a 2-methyl-8-quinolinolato ligand coordinated with a metal chosen from the group Al, Ga, and In, and at least one hole transporting moiety. For example, the compound may be bis(2-methyl-8-quinolinolato)&lsqb;p-(N-phenyl-2-naphthylamino)phenolato&rsqb;aluminum(III), bis(2-methyl-g-quinolinolato)p-carbazolphenolato)aluminum(III), or bis(2-methyl-8-quinolinolato)(m-carbazolphenolato)aluminum(III).

Metal complexes bearing both electron transporting and hole transporting moieties

Organic light emitting devices are disclosed which are comprised of a heterostructure for producing electoluminescence wherein the heterostructure is comprised of an emissive layer containing a dopant compound selected from the class of azlactone-related compounds having the chemical structure as represented by formula I: ##STR1## where R is hydrogen or a donor or acceptor group relative to hydrogen; R'=alkyl or substituted or unsubstituted aryl;

Azlactone-related dopants in the emissive layer of an OLED

The present invention is directed to organic light emitting devices comprised of an electroluminescent layer containing a host material comprised of a metal complex of (5-hydroxy)quinoxaline: ##STR1## wherein M is Al, Ga, In, Zn or Mg, with n=3, if M is Al, Ga or In and n=2, if M is Zn or Mg, and to a method for fabricating such devices.
