Description
本発明は、新規の有機電界発光化合物(organic electroluminescent compound)、およびこれを含む有機電界発光素子(organic electroluminescent device)に関し、より具体的には、正孔輸送材料もしくは正孔注入材料として使用スルのに適する新規の有機電界発光化合物、およびこれを使用する有機電界発光素子に関する。 The present invention relates to a novel organic electroluminescent compound, and an organic electroluminescent device including the same, and more specifically, a hole transport material or a hole injection material. The present invention relates to a novel organic electroluminescent compound suitable for use in an organic electroluminescent device and an organic electroluminescent device using the same.
現在、広く入手可能な液晶ディスプレイ(LCD)は、非放射型ディスプレイ素子であって、これは電力消費が小さくおよび重量が軽いが、複雑な動作システムを有し、かつ満足できない特性、例えば、応答時間およびコントラストを有する。よって、有機電界発光素子が次世代フラットパネルディスプレイとして最近注目を集めており、それについての徹底的な研究が進められている。 Currently widely available liquid crystal displays (LCDs) are non-radiative display elements that have low power consumption and light weight but have complex operating systems and unsatisfactory properties such as response Has time and contrast. Therefore, organic electroluminescence devices have recently attracted attention as next-generation flat panel displays, and thorough research is being conducted on them.
ディスプレイ素子の中では、電界発光(EL)素子は自己発光型ディスプレイ素子として、それが広い視野角、優れたコントラストおよび速い応答速度を提供するという点で有利である。1987年に、イーストマンコダックが、電界発光層を形成するために、低分子量芳香族ジアミンとアルミニウム錯体を使用する有機EL素子を初めて開発した[Appl.Phys.Lett.51,913,1987]。 Among display elements, an electroluminescent (EL) element is advantageous as a self-luminous display element in that it provides a wide viewing angle, excellent contrast and fast response speed. In 1987, Eastman Kodak first developed an organic EL device using a low molecular weight aromatic diamine and an aluminum complex to form an electroluminescent layer [Appl. Phys. Lett. 51, 913, 1987].
有機EL素子の光放射メカニズムは、電子注入電極(カソード)および正孔注入電極(アノード)の間に形成される有機層に電荷が注入され、それにより電子−正孔対を形成し、次いでこの電子−正孔対が消滅して光を放射する。この素子はプラスチックのような可撓性の透明基体上に形成されることができ、かつプラズマディスプレイパネルもしくは無機ELディスプレイよりも低い電圧(10V以下)で駆動することができ、かつ比較的少ない電力消費および優れた色を示しうる。 The light emission mechanism of an organic EL device is such that charges are injected into an organic layer formed between an electron injection electrode (cathode) and a hole injection electrode (anode), thereby forming an electron-hole pair. The electron-hole pair disappears and emits light. This element can be formed on a flexible transparent substrate such as plastic, can be driven at a lower voltage (10 V or less) than a plasma display panel or an inorganic EL display, and has relatively low power. Can show consumption and excellent color.
有機EL素子の有機材料はおおまかに発光材料と電荷発生材料とに分けられる。発光材料は発光色および発光効率に直接関連し、かつそのいくつかの要求事項には、固体相での高い蛍光量子収率、電子および正孔の高移動度、真空蒸着の際の低い分解性、並びに均一で安定な薄膜形成が挙げられる。 The organic material of the organic EL element is roughly divided into a light emitting material and a charge generating material. Luminescent materials are directly related to luminescent color and luminous efficiency, and some requirements include high fluorescence quantum yield in the solid phase, high electron and hole mobility, low decomposability during vacuum deposition And uniform and stable thin film formation.
一方で、正孔注入および輸送材料としては、銅フタロシアニン(CuPc)、NPB、TPD、MTDATA(4,4’,4”−トリス(3−メチルフェニルフェニルアミノ)トリフェニルアミン)などが挙げられる。しかし、この材料が正孔注入および輸送層に含まれている素子は問題があるが、その理由は効率および寿命が低下しているからである。この理由は、有機EL素子が高電流で駆動する場合には、アノードと正孔注入層との間に熱応力が発生し、そしてこの熱応力によって素子の寿命が劇的に短くされうることである。さらに、正孔注入層に使用される有機材料は非常に高い正孔移動度を有し、このことが正孔−電子電荷バランスを失わせ、それにより量子効率(cd/A)を低減させる。 On the other hand, examples of the hole injection and transport material include copper phthalocyanine (CuPc), NPB, TPD, MTDATA (4,4 ′, 4 ″ -tris (3-methylphenylphenylamino) triphenylamine) and the like. However, there is a problem with devices in which this material is included in the hole injection and transport layer, because the efficiency and lifetime are reduced because the organic EL device is driven at a high current. In this case, a thermal stress is generated between the anode and the hole injection layer, and the lifetime of the device can be drastically shortened by this thermal stress. Organic materials have very high hole mobility, which causes a loss of hole-electron charge balance, thereby reducing quantum efficiency (cd / A).
有機EL素子の耐久性を増大させるために、良好な薄膜安定性を有する化合物および高い非結晶化度を有する化合物の使用が、高い薄膜安定性を示すことが報告されている。そのため、ガラス転移温度(Tg)が非結晶性の指標として使用されている。既存のMTDATAは76℃のTgを有し、よって非結晶性を有すると見なされない。これら材料は、正孔注入および輸送特性に基づいて、有機EL素子の耐久性および発光効率の点で満足できない。 In order to increase the durability of the organic EL device, it has been reported that the use of a compound having good thin film stability and a compound having a high degree of non-crystallinity exhibits high thin film stability. Therefore, the glass transition temperature (Tg) is used as an amorphous index. Existing MTDATA has a Tg of 76 ° C. and is therefore not considered non-crystalline. These materials are unsatisfactory in terms of durability and luminous efficiency of the organic EL device based on hole injection and transport characteristics.
よって、本発明は関連する技術分野において遭遇するこれら課題に留意してなされたものであり、そして本発明の目的は、有機EL化合物の骨格が既存の正孔注入または正孔輸送材料よりも発光効率および素子寿命の点で優れている有機EL化合物を提供すること、並びにこの新規の有機EL化合物を正孔注入層もしくは正孔輸送層として使用している有機EL素子を提供することである。 Therefore, the present invention has been made in view of these problems encountered in the related technical field, and the object of the present invention is that the skeleton of the organic EL compound emits light more than an existing hole injection or hole transport material. It is to provide an organic EL compound that is excellent in terms of efficiency and device lifetime, and to provide an organic EL device that uses this novel organic EL compound as a hole injection layer or a hole transport layer.

The organic EL compound according to the present invention is contained in the hole injection layer or the hole transport layer of the organic EL device, thereby lowering the driving voltage of the device and increasing its luminous efficiency.
