Definitions
- the present invention relates to an organic metal complex, in particular to an organic metal complex, a preparation, an organic optoelectronic device and a display or lighting device, and belongs to the field of organic optoelectronics.
- Organic optoelectronic devices especially organic electroluminescent diodes (OLED) have the characteristics of self-illumination, wide viewing angle, low energy consumption, high efficiency, thinness, rich colors, fast response speed, wide applicable temperature range, low driving voltage, and can be manufactured in flexible and The unique advantages of curved and transparent display panels and environmental friendliness can be applied to flat panel displays and new generation lighting, and can also be used as backlight sources for LCDs.
- OLED organic electroluminescent diodes
- OLED Since its invention in the late 1980s, OLED has been used in industry. OLED emits light in two ways: fluorescence and phosphorescence. According to theoretical speculation, the difference between the singlet excited state and the triplet excited state generated by carrier recombination The ratio is 1:3, so when using small molecule fluorescent materials, only 25% of the total energy can be used to emit light, and the remaining 75% of the energy is lost due to the non-luminescent mechanism of the triplet excited state, so it is generally considered that fluorescent materials The internal quantum efficiency limit is 25%. In 1998, Professor Forrest and others discovered that triplet phosphorescence could be utilized at room temperature, and raised the upper limit of the original internal quantum efficiency to 100%.
- Triplet phosphors are often complexes composed of heavy metal atoms, and use the heavy atom effect to strongly
- the spin-orbit coupling effect causes the originally forbidden triplet energy to emit light in the form of phosphorescence, and the quantum efficiency is also greatly improved.
- the luminescent layers in organic OLED components almost all use the host-guest luminescent system mechanism, that is, the host material is doped with the guest luminescent material.
- the energy system of the organic host material is larger than that of the guest material, that is, the energy is transferred from the host to the guest material.
- the object causes the object material to be excited and emit light.
- Commonly used phosphorescent organic host materials have high triplet energy levels. When the organic host material is excited by an electric field, the triplet energy can be effectively transferred from the organic host material to the guest phosphorescent material.
- Commonly used organic guest materials are iridium and platinum metal compounds. However, there are still some technical difficulties in the development of platinum and palladium complex materials and devices. For example, OLED requires high efficiency, long life, and lower operating voltage.

Description
本发明涉及一种有机金属配合物，尤其涉及一种有机金属配合物、制剂、有机光电器件及显示或照明装置，属于有机光电领域。The present invention relates to an organic metal complex, in particular to an organic metal complex, a preparation, an organic optoelectronic device and a display or lighting device, and belongs to the field of organic optoelectronics.
有机光电器件(特别是有机电致发光二极管(OLED))具有自发光、宽视角、低能耗、效率高、薄、色彩丰富、响应速度快，适用温度范围广、低驱动电压、可制作柔性可弯曲与透明的显示面板以及环境友好等独特优点，可以应用在平板显示器和新一代照明上，也可以作为LCD的背光源。Organic optoelectronic devices (especially organic electroluminescent diodes (OLED)) have the characteristics of self-illumination, wide viewing angle, low energy consumption, high efficiency, thinness, rich colors, fast response speed, wide applicable temperature range, low driving voltage, and can be manufactured in flexible and The unique advantages of curved and transparent display panels and environmental friendliness can be applied to flat panel displays and new generation lighting, and can also be used as backlight sources for LCDs.
20世纪80年代底发明以来，OLED已经在产业上有所应用，OLED发光分为荧光发光和磷光发光两种方式，根据理论推测，由载流子复合产生的单重激发态与三重激发态的比例为1:3，所以使用小分子荧光材料时，能用于发光的仅为全部能量的25％，其余的75％的能量因三重激发态的非发光机制而损失掉，故一般认为荧光材料的内部量子效率极限为25％。1998年Forrest教授等人发现三线态磷光可以在室温下利用，并将原来内量子效率的上限提升到100％，三重态磷光体常常都是重金属原子组成的络合物，利用重原子效应，强烈的自旋轨域耦合作用使得原本被禁止的三重态能量以磷光的形式发光，量子效率也随之大幅提升。Since its invention in the late 1980s, OLED has been used in industry. OLED emits light in two ways: fluorescence and phosphorescence. According to theoretical speculation, the difference between the singlet excited state and the triplet excited state generated by carrier recombination The ratio is 1:3, so when using small molecule fluorescent materials, only 25% of the total energy can be used to emit light, and the remaining 75% of the energy is lost due to the non-luminescent mechanism of the triplet excited state, so it is generally considered that fluorescent materials The internal quantum efficiency limit is 25%. In 1998, Professor Forrest and others discovered that triplet phosphorescence could be utilized at room temperature, and raised the upper limit of the original internal quantum efficiency to 100%. Triplet phosphors are often complexes composed of heavy metal atoms, and use the heavy atom effect to strongly The spin-orbit coupling effect causes the originally forbidden triplet energy to emit light in the form of phosphorescence, and the quantum efficiency is also greatly improved.
目前有机OLED组件中的发光层几乎全部使用主客体发光体系机制，即在主体材料中掺杂客体发光材料，一般来说，有机主体材料的能系要比客体材料大，即能量由主体传递给客体，使客体材料被激发而发光。常用的磷光有机主体材料具有高三线态能级，当有机主体材料被电场激发时，三线态能量能够有效地从有机主体材料转移到客体磷光材料。常用的有机客体材料为铱和铂金属化合物。然而铂，钯配合物材料和器件的开发仍然存在一些技术难点，比如OLED要求效率高，寿命长，操作电压更低。At present, the luminescent layers in organic OLED components almost all use the host-guest luminescent system mechanism, that is, the host material is doped with the guest luminescent material. Generally speaking, the energy system of the organic host material is larger than that of the guest material, that is, the energy is transferred from the host to the guest material. The object causes the object material to be excited and emit light. Commonly used phosphorescent organic host materials have high triplet energy levels. When the organic host material is excited by an electric field, the triplet energy can be effectively transferred from the organic host material to the guest phosphorescent material. Commonly used organic guest materials are iridium and platinum metal compounds. However, there are still some technical difficulties in the development of platinum and palladium complex materials and devices. For example, OLED requires high efficiency, long life, and lower operating voltage.
因此，迫切需要开发一种新颖的有机金属配合物。Therefore, there is an urgent need to develop novel organometallic complexes.

In certain aspects, individual substituents can be further optionally substituted (ie, further substituted or unsubstituted) unless expressly stated to the contrary.
在定义各种术语时，“R1”、“R2”、“R3”、“R4”、“R5”和“R”在本发明中作为通用符号来表示各种特定的取代基。这些符号能够是任何取代基，不限于本发明公开的那些，当它们在一个实例中被定义为某些取代基时，在另一个实例中也可以被定义为一些其他取代基。When defining various terms, "R1", "R2", "R3", "R4", "R5" and "R" are used as general symbols in the present invention to represent various specific substituents.

本发明使用的术语“芳基”是6至60个碳原子的取代或未取代的苯基，例如甲基苯基、乙基苯基、正丙基苯基、异丙基苯基、正丁基苯基、异丁基苯基、仲丁基苯基、叔丁基苯基、叔丁基联苯基、正戊基苯基、异戊基苯基、仲戊基苯基、新戊基苯基、己基苯基、庚基苯基、辛基苯基、壬基苯基、癸基苯基、十二烷基苯基、十四烷基苯基、十六烷基苯基、二十烷基苯基、二十四烷基苯基等。The term "aryl" as used herein is a substituted or unsubstituted phenyl group of 6 to 60 carbon atoms, such as methylphenyl, ethylphenyl, n-propylphenyl, isopropylphenyl, n-butyl phenyl, isobutylphenyl, sec-butylphenyl, tert-butylphenyl, tert-butylbiphenyl, n-pentylphenyl, isopentylphenyl, sec-pentylphenyl, neopentyl Phenyl, hexylphenyl, heptylphenyl, octylphenyl, nonylphenyl, decylphenyl, dodecylphenyl, tetradecylphenyl, hexadecylphenyl, eicosanyl Alkylphenyl, tetradecylphenyl, etc.

That is, when a term such as "cycloalkyl" refers to both unsubstituted and substituted cycloalkyl moieties, the substituted moiety may otherwise be specifically identified in the present invention; for example, a specifically substituted cycloalkyl group may be referred to as For example, "alkylcycloalkyl". Similarly, a substituted alkoxy group may be specifically referred to as, for example, a "haloalkoxy group" and a specific substituted alkenyl group may be, for example, an "enol" or the like.
