Quinoline derivatives and organic electroluminescent devices |
摘要 |
Quinoline derivatives represented by formula (1) wherein two or more of substituents R1 to R7 are each a group of formula (2). In general formula (2), Q is a carbo- or hetero-aryl group; and the number (n) of double bonds is preferably 1 to 3. Use of such derivatives in an organic EL device provided with a layer of an organic compound and two electrodes sandwiching the layer as the organic compound gives devices emitting yellow to red light with high brightness and high efficiency. Further, doping a hole transport layer with such derivatives realizes organic EL devices capable of emitting lights of resultant colors (e.g., white) composed of lights from light-emitting and hole transport layers.
