A fluoranthene compound with a specified asymmetric structure; an organic EL device which is composed of one or more organic compound layers including at least one emitting layer sandwiched between a pair of electrodes, wherein at least one of the organic compound layers contains at least one kind of the fluoranthene compound; and a solution containing a material for the organic EL which is composed of the fluoranthene compound as the material for the organic EL and a solvent. An organic electroluminescence (EL) device having a superior luminance of light emission, an enhanced efficiency of light emission, and a prolonged lifetime and a compound realizing the device are provided.
An organic electroluminescent device including, a cathode, an anode, and at least an emitting layer and an electron transporting layer between the cathode and the anode, the emitting layer including a host compound and a fluoranthene compound, the electron transporting layer including a compound represented by (A)u-(B)v wherein A is a group containing an aromatic hydrocarbon group having 3 or more carbon rings, B is a heterocyclic group which may be substituted, and u and v are each an integer of 1 to 6.
An organic EL device includes: an anode for injecting holes; a phosphorescent-emitting layer; a fluorescent-emitting layer; and a cathode for injecting electrons. The phosphorescent-emitting layer contains a phosphorescent host and a phosphorescent dopant for phosphorescent emission. The fluorescent-emitting layer contains a fluorescent host and a fluorescent dopant for fluorescent emission. The fluorescent host is at least one of an asymmetric anthracene derivative represented by a formula (1) below and a pyrene derivative represented by a formula (2) below.
