Patent abstract
An OLED device comprises a cathode, an anode, and a light-emitting layer therebetween, and additionally comprises a layer between the cathode and the light-emitting layer including a compound comprising one and only one anthracene nucleus bearing no more than two phenanthroline-containing substituents wherein said anthracene nucleus is substituted in the 2-, 3-, 6-, or 7-position with a phenanthroline-containing substituent. When such materials are included in a layer, such as an electron-transporting layer, that provide both desirable electroluminescent properties as well as good device stability.
