Abstract
An organic electroluminescent device of the type which comprises an organic layer having a luminescent region provided between an anode and a cathode, characterized in that the organic layer contains a distyryl compound represented by the following general formula (1): wherein, in the above general formula (1), R1, R2, R3 and R4 are, respectively, of groups which may be the same or different and represent an aryl group of the following general formula (2): wherein, in the above general formula (2), R5, R6, R7, R8 and R9 are, respectively, of groups which may be the same or different and represent a hydrogen atom, or at least one of them is a saturated or unsaturated alkoxyl group or an alkyl group.
Claims8
An organic electroluminescent device comprising:
- a cathode and an anode,
- an organic layer having a luminescent region and disposed between the anode and the cathode, the organic layer comprising a distyryl compound having a general formula (1):
- wherein R1, R2, R3 and R4 comprise an aryl group of a general formula (2)
- wherein R5, R6, R7, R8 and R9 are selected from the group consisting of a hydrogen atom, a saturated alkoxyl group, an unsaturated alkoxy group, a saturated alkyl group and an unsaturated alkyl group;
- and
- wherein the distyryl groups are bonded exclusively at the 2,6 positions of the central anthracenylene core and are not bonded at any other position of the core.
An organic electroluminescent device comprising:
- a cathode and an anode,
- an organic layer comprising a luminescent region disposed between the anode and the cathode, the organic layer further comprising two distryryl compounds wherein the distyryl compounds are bonded exclusively at the 2,6 positions of the central anthracenylene core and are not bonded at any other position of the core;
- and at least one distyryl compound selected from the group consisting of:
