Patent ID: 8889268

Claim:
An organic electroluminescence element, comprising: a pair of electrodes; and an organic light emitting layer, the organic light emitting layer being a multilayer structure made of an organic material held between said pair of electrodes, wherein, the organic material contains at least one of a material represented by the general formula (1), and a material represented by the general formula (2),general formulae (1) and (2) being: where (a) each of Ar 1 to Ar 3 represent a phenyl group, a naphthyl group, a phenanthrenyl group, and an anthracenyl group and each of the phenyl group, the naphthyl group, the phenanthrenyl group, and the anthracenyl group may include an alkyl group having a carbon number of 6 or less or an organic compound group of 14-th group elements each heavier than carbon is adapted to be substituent, and (b) each of R 1 to R 18 represent a hydrogen, an alkyl group having a carbon number of 6 or less or a phenyl group including an alkyl group having the carbon number of 6 or less as a substituent, and at least one of R 2 and R 5 , and R 8 and R 11 is not hydrogen, and where (a) each of R 1 to R 33 represent a hydrogen, an alkyl group having a carbon number of 6 or less, a phenyl group, a naphthyl group, a phenanthrenyl group, and an anthracenyl group and where each of the phenyl group, the naphthyl group, the phenanthrenyl group, and the anthracenyl group may include an alkyl group having a carbon number of 6 or less or an organic compound group of 14-th group elements each heavier than carbon as a substituent, (b) at least one of R 9 R 20 or R 31 represents β-H, where the β-H is attached at the β position of a function group, and (c) at least one of R 4 , R 15 or R 26 represents hydrogen or an alkyl group having the carbon number of 6 or less.
