Abstract
An organic electroluminescent element includes a light emitting layer including, as host materials, an anthracene-based compound represented by the following general formula (1) and a dibenzochrysene-based compound represented by the following general formula (2), and further including a dopant material. (X and Ar4 in formula (1) each represent a hydrogen atom, an optionally substituted aryl, or the like, and R1 to R16 in formula (2) each represent a hydrogen atom, an aryl, or the like.)
Claims19
An organic electroluminescent element including a pair of electrode layers composed of a positive electrode layer and a negative electrode layer and a light emitting layer disposed between the pair of electrodes, in which the light emitting layer includes, as host materials, an anthracene-based compound represented by the following general formula (1) and a dibenzochrysene-based compound represented by the following general formula (2), and further includes a dopant material.
- (In the above formula (1),
- X and Ar4 each independently represent a hydrogen atom, an optionally substituted aryl, an optionally substituted heteroaryl, an optionally substituted diarylamino, an optionally substituted diheteroarylamino, an optionally substituted arylheteroarylamino, an optionally substituted alkyl, an optionally substituted alkenyl, an optionally substituted alkoxy, an optionally substituted aryloxy, an optionally substituted arylthio, or an optionally substituted silyl, while not all the X's and Ar4's represent hydrogen atoms simultaneously, and
- at least one hydrogen atom in the compound represented by formula (1) may be substituted by a halogen atom, a cyano, a deuterium atom, or an optionally substituted heteroaryl.)
- (In the above formula (2),
- R1 to R16 each independently represent a hydrogen atom, an aryl, a heteroaryl (the heteroaryl may be bonded to the dibenzochrysene skeleton in the above formula (2) via a linking group), a diarylamino, a diheteroarylamino, an arylheteroarylamino, an alkyl, an alkenyl, an alkoxy, or an aryloxy, while at least one hydrogen atom in these may be substituted by an aryl, a heteroaryl, or an alkyl,
- adjacent groups out of R1 to R16 may be bonded to each other to form a fused ring, and at least one hydrogen atom in the formed ring may be substituted by an aryl, a heteroaryl (the heteroaryl may be bonded to the formed ring via a linking group), a diarylamino, a diheteroarylamino, an arylheteroarylamino, an alkyl, an alkenyl, an alkoxy, or an aryloxy, while at least one hydrogen atom in these may be substituted by an aryl, a heteroaryl, or an alkyl, and
- at least one hydrogen atom in the compound represented by formula (2) may be substituted by a halogen atom, a cyano, or a deuterium atom.)
