Definitions
- the invention relates to a novel tetradentate platinum (II) complex metal organic material based on oxazole, thiazole and imidazole, which is mainly used in an OLED light-emitting device as a phosphorescent dopant material in a light-emitting layer.
- II tetradentate platinum
- OLED Organic Light-Emitting Diode
- OLED display technology has the advantages of self-luminous, wide viewing angle, almost infinite contrast, low power consumption, high reaction speed, etc.
- OLED has potential flexible folding characteristics, and thus has been widely concerned and studied, but OLED
- the shortcomings of short service life, poor color purity, and aging are hindering the large-scale application of OLED technology. Therefore, designing new OLED materials is the focus and difficulty of OLED research.
- platinum (II)-based phosphorescent OLED materials have shown good display performance in recent years.
- Platinum (II) is generally a tetracoordinated site, and a metal organoplatinum (II) complex having a unique configuration can be formed by designing a tetradentate ligand.
- the common tetradentate ligands are mainly O ⁇ N ⁇ N ⁇ O, O ⁇ N ⁇ C ⁇ O, O ⁇ N ⁇ C ⁇ N and the like.
- O ⁇ N ⁇ N ⁇ O tetradentate platinum (II) complexes are mainly Schiff bases, which are relatively common, but the stability is relatively poor; O ⁇ N ⁇ C ⁇ O four teeth Platinum (II) complexes are relatively stable, but performance needs to be improved.
- the designed and synthesized N ⁇ N ⁇ N ⁇ O configuration tetradentate platinum (II) complex is a novel coordination mode, showing good stability and luminescence properties.
- O ⁇ N ⁇ N ⁇ O tetradentate platinum (II) complexes are mainly Schiff bases, which are relatively common, but the stability is relatively poor; O ⁇ N ⁇ C ⁇ O and O ⁇ The N ⁇ C ⁇ N tetradentate platinum (II) complex is relatively stable, but its performance needs to be improved.
- the general O ⁇ N ⁇ C ⁇ N configuration of tetradentate platinum (II) complexes the structure of which is mainly composed of six-membered aromatic ring ligands.
- a novel tetradentate platinum (II) complex based on a five-membered aromatic ring derivative oxazole, thiazole and imidazole is designed and synthesized, and exhibits good stability and luminescence properties.
- the invention designs a novel O ⁇ N ⁇ C ⁇ N tetradentate platinum (II) complex material based on oxazole, thiazole and imidazole, and can be applied as a phosphorescent dopant material in the field of OLED.
- the organometallic complex has high fluorescence quantum efficiency, good thermal stability and low quenching constant, and can manufacture a yellow-green light OLED device with high efficiency and low efficiency roll-off.
- the invention also provides a preparation method of the novel platinum (II) complex.
- a 1 -A 4 is a substituted or unsubstituted five-membered ring, six-membered ring, fused ring structure;

Description
本发明涉及一种新型基于恶唑、噻唑和咪唑的四齿铂(II)配合物金属有机材料,主要是用于OLED发光器件中,作为发光层中的磷光掺杂材料。
有机发光二极管(Organic Light-Emitting Diode,OLED)又称为有机电激光显示、有机发光半导体,由美籍华裔教授邓青云(Ching W.Tang)于1979年在实验室中发现。OLED显示技术具有自发光、广视角、几乎无穷高的对比度、较低耗电、极高反应速度等优点,尤其是OLED具有潜在的柔性可折叠特性,因而一直受到广泛的关注与研究,但是OLED存在使用寿命短、色彩纯度差、易老化等缺点,阻碍了OLED技术的大规模应用。因此,设计新型的OLED材料,则是OLED领域研究的重点与难点。
其中,近些年来基于铂(II)的磷光OLED材料表现出了较好的显示性能。铂(II)一般为四配位点,可以通过设计四齿配体形成具有唯一构型的金属有机铂(II)配合物。一般而言,常见的四齿配体主要有O^N^N^O,O^N^C^O,O^N^C^N等类型。其中,O^N^N^O类四齿铂(II)配合物主要为席夫碱(Schiff base)l类,较为常见,但稳定性相对较差;O^N^C^O类四齿铂(II)配合物相对较为稳定,但性能有待提升。本发明中,设计和合成的N^N^N^O构型四齿铂(II)配合物,则是一种新型配位模式,表现出了较好的稳定性和发光性能。其中,O^N^N^O类四齿铂(II)配合物主要为席夫碱(Schiff base)类,较为常见,但稳定性相对较差;O^N^C^O类和O^N^C^N四齿铂(II)配合物相对较为稳定,但性能有待提升。其中,一般的O^N^C^N构型四齿铂(II)配合物,其结构主要是以六元芳香环配体为主。在本发明专利中,则是设计合成了一种新型的基于五元芳香环衍生物恶唑、噻唑和咪唑的四齿铂(II)配合物,并表现出了较好的稳定性和发光性能。

对于实施例的Pt(II)配合物,在二氯甲烷溶液溶液中呈现出明显的黄绿光发射,波长范 围在528~531nm之间。其中,Pt-0为参比O^N^C^O类黄绿光材料。如下表所示:
下面是本发明配合物的应用实例。
器件制备方式:
器件的基本结构模型为:ITO/HTL-1(60nm)/EML-1:Pt(II)(40nm)/ETL-1(30nm)/LiF(1nm)/Al(80nm)。
依次使用丙酮、乙醇和蒸馏水对透明阳极氧化铟锡(ITO,20)(10Ω/sq)玻璃基板10进行超声清洗,再用氧气等离子处理5分钟。
然后将ITO衬底安装在真空气相蒸镀设备的衬底固定器上。在蒸镀设备中,控制体系压力在10
-6torr.。
此后,向ITO衬底上蒸发厚度为60nm的空穴传输层(30)材料HTL-1。
然后蒸发厚度为40nm的发光层材料(40)EML-1,其中掺杂一定质量分数的铂(II)配合物掺杂剂。
然后蒸发厚度为30nm的电子传输层(50)材料ETL-1。
然后蒸发厚度为1nm的LiF为电子注入层(60)。
最后蒸发厚度为80nm的Al作为阴极(70)并完成器件封装。
其中,
器件的结构和制作方法完全相同,区别在于依次使用有机金属配合物Pt-0、TM-1,TM-2,TM-3,TM-4作为发光层中的掺杂剂和惨杂浓度。
器件对比结果下表所示:
在四齿铂(II)配合物掺杂浓度分别为10wt%,15wt%,20wt%条件下,以上述ITO/HTL-1(60nm)/EML-1:Pt(II)(40nm)/ETL-1(30nm)/LiF(1nm)/Al(80nm)器件基本结构制备器件。以基于Pt-0的器件性能为参考,基于恶唑、噻唑和咪唑的四齿铂(II)配合物TM-1,TM-2,TM-3,TM-4的器件在启动电压V
on相比Pt-0的器件有一定的降低,尤其是基于TM-4的器件其启动电压降至2.7V。同时,在1000cd/A条件下,基于TM-1,TM-2,TM-3,TM-4的器件在电流效率(CE),功率效率(PE)和外量子效率(EQE)相对于基于Pt-0的器件均有不同程度的提升,尤其是TM-4,在电流效率(CE),功率效率(PE)和外量子效率(EQE)上提升较为明显。在四齿铂(II)配合物掺杂浓度增加时,Pt-0,TM-1,TM-2,TM-3的效率提升较小甚至Pt-0,TM-1,TM-2的效率有一定程度的下降,但是TM-3和TM-4有较好的效率提升,尤其是TM-4,其电流效率由94.0cd/A提升至102.3cd/A,功率效率由78.0lm/W提升至86.5lm/W,外量子效率由21.5%提 升至25.8%。TM-4相对于Pt-0,TM-1,TM-2,TM-3在空间上有较大的位阻基团,能有效降低分子间的聚集作用,避免形成激基复合物,提高发光效率,因而TM-4在相同的器件上具有最好的性能。同时,TM-1,TM-2,TM-3相对于Pt-0在性能上也有不同程度的提升,说明基于恶唑、噻唑和咪唑的O^N^C^N类四齿铂(II)配合物具有较为广阔的应用前景和商业价值。
