Description
本発明は、新規なカルバゾール化合物、その製造法、及びその用途に関するものである。 The present invention relates to a novel carbazole compound, a production method thereof, and an application thereof.
本発明のカルバゾール化合物は、特に、燐光材料を用いた有機ＥＬ素子に対して非常に有用である。 The carbazole compound of the present invention is particularly useful for an organic EL device using a phosphorescent material.
有機ＥＬ素子は、次世代の薄型平面ディスプレイとして現在盛んに研究されており、既に携帯電話のディスプレイやテレビ、照明等への実用化も始まっている。特に最近では、発光効率を向上させるため、燐光発光材を用いた素子開発が活発化してきている。 Organic EL devices are currently being actively studied as next-generation thin flat displays, and have already been put into practical use for mobile phone displays, televisions, lighting, and the like. In particular, recently, in order to improve luminous efficiency, element development using a phosphorescent material has been activated.
燐光発光材を用いた有機ＥＬ素子では、蛍光発光材を用いた有機ＥＬ素子に比べて、三重項準位（Ｔ１）が高いキャリア輸送材（例えば、正孔輸送材料）と燐光発光材を組み合わせることが好ましい。例えば、正孔輸送材料として良く知られている４，４’−ビス［Ｎ−（１−ナフチル）−Ｎ−フェニルアミノ］ビフェニル（α−ＮＰＤ）のＴ１は２．３ｅＶ程度であるが、α−ＮＰＤと燐光発光材を組み合わせた有機ＥＬ素子の場合、発光層に三重項励起エネルギーを十分に閉じ込められず、燐光発光有機ＥＬ素子で期待される高い外部量子効率が得られないことが知られている（例えば、非特許文献１参照）。このため、α−ＮＰＤより高いＴ１を有する正孔輸送材が強く望まれている。 In an organic EL element using a phosphorescent material, a carrier transport material (for example, a hole transport material) having a higher triplet level (T1) is combined with a phosphorescent material than an organic EL element using a fluorescent material. It is preferable. For example, T1 of 4,4′-bis [N- (1-naphthyl) -N-phenylamino] biphenyl (α-NPD), which is well known as a hole transport material, is about 2.3 eV. In the case of an organic EL device in which -NPD and a phosphorescent material are combined, it is known that triplet excitation energy is not sufficiently confined in the light emitting layer, and the high external quantum efficiency expected in the phosphorescent organic EL device cannot be obtained. (For example, refer nonpatent literature 1). For this reason, a hole transport material having T1 higher than α-NPD is strongly desired.
正孔輸送材としては、カルバゾール環を有するトリアリールアミン化合物の開発が行われている（例えば、特許文献１、化合物１）。しかしながら、発明者らの測定によると、化合物１のＴ１は２．３ｅＶであり、当該化合物より高いＴ１を有する化合物の開発が求められていた。 As a hole transport material, development of a triarylamine compound having a carbazole ring has been performed (for example, Patent Document 1, Compound 1). However, according to the measurement by the inventors, the T1 of the compound 1 is 2.3 eV, and the development of a compound having a higher T1 than that of the compound has been demanded.
本発明は上記の背景技術に鑑みてなされたものであり、その目的は、高いＴ１を有す新規なカルバゾール化合物、その製造方法、及びその用途を提供することにある。 The present invention has been made in view of the background art described above, and an object thereof is to provide a novel carbazole compound having a high T1, a production method thereof, and an application thereof.
