- the present invention relates to an electroluminescence element.
- organic electroluminescent elements are self-luminous elements, they have been actively researched because they are brighter and have better visibility than liquid crystal elements and can be clearly displayed.
- an organic electroluminescence element carriers are injected into a luminescent material from both positive and negative electrodes to generate an excited luminescent material and emit light.
- 25% of the generated excitons are excited to the excited singlet state, and the remaining 75% are excited to the excited triplet state. ing. Therefore, it is considered that the use efficiency of energy is higher when phosphorescence, which is light emission from an excited triplet state, is used.
- phosphorescence generally has a high quantum yield because the excited triplet state has a long lifetime, which results in saturation of the excited state and energy deactivation due to interaction with excitons in the excited triplet state. .
- an organic electroluminescence element using a material exhibiting delayed fluorescence can be considered.
- the latter material that exhibits thermally activated delayed fluorescence is considered to be particularly useful.
- excitons in the excited singlet state emit fluorescence as usual.
- excitons in the excited triplet state absorb heat generated by the device, cross the system into excited singlets, and emit fluorescence.
- the light is emitted from the excited singlet, it is emitted at the same wavelength as the fluorescence, but the lifetime of light generated by the cross-system crossing from the excited triplet state to the excited singlet state, that is, the emission lifetime is usually Since the fluorescence becomes longer than the fluorescence and phosphorescence, it is observed as fluorescence delayed from these. This can be defined as delayed fluorescence.

Abstract
Description
1993年にプリンストン大学のM.A.Baldoらは、イリジウム錯体を用いた燐光発光素子によって8%の外部量子効率を実現させた。
また、熱活性化遅延蛍光(TADF)による発光を利用する素子も開発されている。2011年に九州大学の安達らは、熱活性化遅延蛍光材料を用いた素子によって5.3%の外部量子効率を実現させた(例えば、非特許文献1参照)。
そこで、遅延蛍光を示す材料を利用する有機エレクトロルミネッセンス素子が考えられる。ある種の蛍光物質は、系間交差などにより励起三重項状態へとエネルギーが遷移した後、三重項-三重項消滅あるいは熱エネルギーの吸収により、励起一重項状態に逆系間交差され蛍光を放射する。有機エレクトロルミネッセンス素子においては、後者の熱活性化型の遅延蛍光を示す材料が特に有用であると考えられる。ここで、有機エレクトロルミネッセンス素子に遅延蛍光材料を利用した場合、励起一重項状態の励起子は通常通り蛍光を放射する。一方、励起三重項状態の励起子は、デバイスが発する熱を吸収して励起一重項へ系間交差され蛍光を放射する。この場合、励起一重項からの発光であるため蛍光と同波長での発光でありながら、励起三重項状態から励起一重項状態への逆系間交差により、生じる光の寿命、すなわち発光寿命は通常の蛍光や燐光よりも長くなるため、これらよりも遅延した蛍光として観察される。これを遅延蛍光として定義できる。このような熱活性化型の励起子移動機構を用いること、すなわち、キャリア注入後に熱エネルギーの吸収を経ることにより、通常は25%しか生成しなかった励起一重項状態の化合物の比率を25%以上に引き上げることが可能となる。100℃未満の低い温度でも強い蛍光および遅延蛍光を発する化合物を用いれば、デバイスの熱で充分に励起三重項状態から励起一重項状態への系間交差が生じ、遅延蛍光を放射することから、発光効率が飛躍的に向上する(例えば、特許文献1および特許文献2参照)。
