Abstract
An organic electroluminescence element includes: a pair of electrodes; and an organic light emitting functional layer structured as a multilayer structure made of an organic material held between the pair of electrodes, and containing at least one of a material represented by the general formula (1), and a material represented by the general formula (2) in the multilayer structure.
Claims7
An organic electroluminescence element, comprising:
- a pair of electrodes;
- and
- an organic light emitting functional layer structured as a multilayer structure made of an organic material held between said pair of electrodes, and containing at least one of a material represented by the general formula (1), and a material represented by the general formula (2) in said multilayer structure
- in which Ar1 to Ar3 are substituent groups which are selected from a phenyl group, a naphthyl group, a phenanthrenyl group, and an anthracenyl group and for which either 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 substituted, and R1 to R18 are hydrogen, an alkyl group having a carbon number of 6 or less or a phenyl group for which the alkyl group having the carbon number of 6 or less is adapted to be substituted, but at least one of the substituent groups of R2 and R5, and R8 and R11 is a substituent group other than hydrogen,
- in which R1 to R33 are substituent groups which are selected from hydrogen, the alkyl group having the carbon number of 6 or less, and a phenyl group, a naphthyl group, a phenanthrenyl group, and an anthracenyl group for which either 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 substituted.
2 more elements
A display device, comprising:
- organic electroluminescence elements each including an organic light emitting functional layer in which at least one of a material represented by the general formula (1), and a material represented by the general formula (2) is contained in a multilayer structure made of an organic material held between a pair of electrodes, said organic electroluminescence elements being arranged on a substrate
- in which Ar1 to Ar3 or R1 to R18 are substituent groups which are selected from a phenyl group, a naphthyl group, a phenanthrenyl group, and an anthracenyl group and for which 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 be substituted, and R1 to R18 are hydrogen, an alkyl group having a carbon number of 6 or less, or a phenyl group for which the alkyl group having the carbon number of 6 or less is adapted to be substituted, but at least one of the substituent groups of R2 and R5, and R8 and R11 is a substituent group other than hydrogen,
- in which R1 to R33 are substituent groups which are selected from hydrogen, the alkyl group having the carbon number of 6 or less, and a phenyl group, a naphthyl group, a phenanthrenyl group, and an anthracenyl group for which either 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 substituted.
