Description
技术领域
本发明属于光电材料应用科技领域,具体涉及一种含有苯并杂环结构的有机光电材料及其制备方法和应用。
背景技术
有机电致发光器件(OLED)是一门新型显示技术,具有超薄、高亮度、宽视角、自发光、低功耗、低成本、可弯曲及在低温条件下(TFT-LCD中的液晶在这类条件下会凝固)能够正常工作等优越性能,被业界誉为LCD之后理想的和最具发展前景的下一代显示技术。
作为三基色之一的蓝光,一直比绿光和红光OLED发展滞后,存在与需要解决的问题也比较多,这是由蓝光OLED本身的性质决定的。不管是荧光还是磷光材料,深蓝色的染料都非常缺乏,使得在制备显示面板的过程中,深蓝光的材料选择较少,同时大部分蓝光材料的效率也相对较低。蓝光材料的能级差一般都比较大,为了避免能量回传,只能选择比发光材料能级更大的主体材料,这样就会导致在蓝光层两边形成的界面能极差很大,容易导致载流子的积累,产生三重态-三重态激子严重湮灭即效率滚降问题,严重影响器件的工作寿命。另外,由于蓝光材料自身的宽禁带,纯蓝光/深蓝光材料通常会有较低的HOMO与较高的LUMO能级,这种能级结构一方面加大了从功能层向发光层注入载流子的势垒,导致驱动电压升高,载流子传输困难、平衡度降低;另一方面,易在发光层与功能层界面处产生激基复合物发射,这不仅会使OLED发光颜色不纯(大于470nm),也会引起器件效率的降低。因此针对效率降滚和光色品质问题的蓝光材料的进一步开发是目前OLED领域研究的热点。
发明内容
本发明所要解决的技术问题是针对上述现有技术的不足,本发明提供了一种含有苯并杂环结构的有机光电材料及其制备方法和应用。
本发明解决上述技术问题的技术方案如下:一种含有苯并杂环结构的有机光电材料,结构通式如下:
其中,L为取代或未取代的杂环化合物,且所述L和与其相连的苯环之间并环连接;
Ar为取代或未取代的亚稠合芳香基;
R为氢、烷基、烷氧基中的任意一种。
作为本发明的一种优选的技术方案,所述L为取代或未取代的五元酯杂环或六元酯杂环,其中,所述五元酯杂环或六元酯杂环中的杂原子为氮、氧、硫和/或硒。
作为本发明的一种优选的技术方案,所述L为未取代的或由烷基或芳香基取代的哌嗪、未取代的或由烷基或芳香基取代的二氧六环、未取代的或由烷基或芳香基取代的噻噁烷、未取代的或由烷基或芳香基取代的二噻烷、未取代的或由烷基或芳香基取代的吗啉、未取代的或由烷基或芳香基取代的硫代吗啉、未取代的或由烷基或芳香基取代的四氢吡喃、未取代的或由烷基或芳香基取代的四氢噻喃、未取代的或由烷基或芳香基取代的哌啶、未取代的或由烷基或芳香基取代的四氢呋喃、未取代的或由烷基或芳香基取代的四氢噻吩、未取代的或由烷基或芳香基取代的四氢硒吩、未取代的或由烷基或芳香基取代的四氢吡咯中的一种。
作为本发明的一种优选的技术方案,所述Ar为取代或未取代的亚萘基、取代或未取代的亚蒽基、取代或未取代的亚菲基、取代或未取代的亚芘基、取代或未取代的亚苯并蒽基中的一种。
更具体的,所述含有苯并杂环结构的有机光电材料为如下化合物1-化合物129中的任意一种:
本发明所提供的含有苯并杂环结构的有机光电材料通过如下路线合成:
其中,L为取代或未取代的杂环化合物,且所述L和与其相连的苯环之间并环连接;
Ar为取代或未取代的亚稠合芳香基;
R为氢、烷基、烷氧基中的任意一种。
具体制备方法为:将菲醌、苯并杂环对应的胺化物、R和Ar对应取代的醛化物、醋酸铵按照摩尔比1:1.1:1.1:2溶解在醋酸中并加至反应器,在氮气氛围下,升温至100-120℃,并在100-120℃下反应8h-20h,液相监测菲醌无剩余后,冷却至室温,用乙醇打浆一遍,再用体积比为10:1的乙醇和乙酸乙酯的混合液打浆一遍或两遍,得到含有苯并杂环结构的有机光电材料,其中,所述醋酸的质量为所述菲醌质量的8-15倍。
需要说明的是,菲醌微溶于乙醇、乙酸乙酯以及热的醋酸,苯并杂环对应的胺化物以及R和Ar对应取代的醛化物均易溶于乙醇,用乙醇及乙酸乙酯可充分实现目标化合物的提纯,有效避免柱层析工序的复杂性,工艺简单,易实现工业化生产。
本发明所提供的含有苯并杂环结构的有机光电材料的应用于制作有机电致发光器件和/或有机太阳能电池。
作为一种优选的技术方案,所述有机电致发光器件包括发光层,所述发光层的材料独自的为本发明提供的含有苯并杂环结构的有机光电材料,或者经由本发明提供的含有苯并杂环结构的有机光电材料掺杂形成。
本发明的优势在于,同时在菲并咪唑的五元芳杂环的氮原子位点上引入稠环芳烃和碳原子位点上引入苯并酯杂环,保留菲并咪唑这一深蓝光生色团本身的热学稳定性和荧光量子效率外,一方面,未参与共轭的酯杂环破坏了分子的平面共轭结构,产生的空间位阻使其二面角增大,平面发生扭曲,抑制分子间π-π*堆积,增强发光亮度的同时,HOMO和LUMO分别离域在给体和受体上,导致一个小的ΔEst(最低激发单重态和最低激发三重态的能级差),提升热致延迟机理(RISC)产生的荧光量子效率,另一方面,苯并酯杂环可有效改善稠环体系在固态下强的聚集行为以及分子内电荷转移过程,通过结构设计提供了一个大的三重态浓度,为利用三重态-三重态湮灭机制(TTA)实现大电流密度下较高的荧光量子效率,进而设计高亮度、长寿命的器件提供了有利的条件。本发明创新性的将苯并酯杂环应用至有机电致发光器件中,实现RISC和TTA共存体系电致发光,为获得高的光电转换效率和解决目前深蓝光材料效率降滚和光色品质问题开辟了新途径。

将直流电通入器件,进行器件的性能评价,如下表:
表有机电致发光器件性能表征
由表中可以看出,本发明所提供的含有苯并杂环结构的有机发光材料独立的作为发光层材料或者作为发光层主/客体材料均表现出高亮度的深蓝光的同时,在启动电压、电流效率以及外量子效率等性能方面较之传统的深蓝光OLED器件亦有显著的进步,可作为发光层主/客体材料进行优良性能的器件制备之外,尤其适用于独立的作为发光层材料进行非掺杂器件的制备。此外,本发明提供的含有苯并杂环结构的有机发光材料在简单结构的器件上表现出优异的色坐标(0.16,0.04)即404nm的蓝光光色,在色坐标y值上具有显著的进步。
需要说明的是,如图1所示,以ITO/m-MTDATA(5nm)/NPB(60nm)/化合物3或者CBP:5%wtBCzVB(20nm)/TPBi(30nm)/LiF(1nm)/Al(100nm)为结构制备的器件的能级图,由此可见,与传统的蓝光荧光掺杂材料相比,本发明提供的含有苯并杂环结构的有机光电材料通过结构设计具有较低的LUMO能级和HOMO能级,降低了功能层之间的载流子注入势垒,平衡的载流子传输平衡性有效避免了独立本发明提供的化合物独立作为发光层材料时激子在非发光层的消耗和湮灭,提高发光效率,同时,作为发光层客体材料使用时,比4,4'-二(2,2-二苯乙烯基)-1,1'-联苯(DPVBi)、CBP等传统发光层主体材料低的HOMO能级有效抑制了客体材料将三重态激子能量回传给主体材料,在器件制备中具有广泛的使用性。如图2所示,本发明提供的含有苯并杂环结构的有机光电材料独立的作为发光层材料制备的器件与传统蓝光器件相比,共轭长度的缩短有效增加了材料的禁带宽度,波长发生了明显的蓝移,使器件发出450nm的饱和蓝光。如图3和图5所示,本发明提供的含有苯并杂环结构的有机光电材料独立的作为发光层材料制备的器件与传统蓝光器件相比,由于较大的扭曲结构增大了空间位阻,有效抑制分子间聚集,通过RISC和TTA共存体系电致发光体制提高了固态荧光量子产率及激子利用率,发光强度达到55880cd/m2,外量子效率提高至5.70%。如图4所示,本发明提供的含有苯并杂环结构的有机光电材料独立的作为发光层材料制备的器件与传统蓝光器件相比,具有平衡的载流子传输性能,在电流效率与流明效率分别高达16.44cd/A、6.86lm/W。
以上所述仅为本发明的较佳实施例,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
