本发明提供了显示高的空穴迁移率和/或高的玻璃化转变温度以及有利的HOMO、LUMO和三线态能级的化合物,它们是2‑(4'‑二苯基氨基)苯基‑8‑(1'‑噻蒽基)‑二苯并噻吩和4‑(1‑噻蒽基)‑联(三苯基胺)。所述化合物可以用于例如OLED器件中的空穴传输层。
Description
发明领域
本发明涉及新型化合物和它们在电光或光电器件中的应用,尤其是在光学发光器件如在空穴传输层中的应用。
发明背景
空穴传输材料
一类空穴传输材料包含包括至少两个芳族叔胺结构部分的芳族叔胺(例如基于联苯二胺的那些或“星放射状”结构的那些),它们中以下化合物是代表性的,并且此时它们中的α-NPB[Tg(℃)98,μh(cm2V-1s-1)1x 10-4]据信是最广泛接受的和用在商业生产中。
WO2014/167286(Kathirgamanathan,其公开内容通过引用结合在本文中)关注提供更多具有空穴传输性能的化合物或者在备选的方案中提供改进的具有空穴传输性能的化合物的问题,并且除其它外公开了空穴传输材料,该空穴传输材料具有连接到除烷基取代的芴外的共轭或芳族烃的一个、两个或三个噻蒽结构部分。所述化合物的一些实施方案据说显示了令人惊讶地有利的空穴迁移率和高玻璃化转变温度或熔点的组合,使得它们可以用在空穴注入层和/或用在电子封闭层。因为它们通常是小分子,它们中的许多可通过升华纯化,这对于OLED和其它器件应用所要求的纯度的化合物的生产来说是希望的。所报道的具体化合物包括:4-(噻蒽-1-基)三苯基胺(也称为二苯基-(4-噻蒽-1-基苯基)胺)(HTS-1);4,4',4”-三(噻蒽-1-基)三苯基胺(也称为三(4-噻蒽-1-基苯基)胺;HTS-2);9-(4-噻蒽-1-基苯基)-9H-咔唑(HTS-3);4,4'-二(噻蒽-2-基)三苯基胺(苯基-二(4-噻蒽-1-基苯基)胺;HTS-4);4-(10H-吩噻嗪-10-基)三苯基胺(N-(4-(10H-吩噻嗪-10-基)苯基)-N-苯基苯胺;HTS-5);和2,8-二(1-噻蒽基)二苯并噻吩[HTS-8]。与α-NPB相比较的HOMO和LUMO能级显示如下。
Kathirgamanathan中关于盒结构、阳极、空穴注入体和空穴传输层、空穴注入材料、电致发光材料、电子传输材料、电子注入材料和阴极的一般教导通过引用全部结合到本文中。
发明概述
本发明提供了除WO 2014/167286中描述的种类外且据信改进的、基于噻蒽的化合物。
在一个方面,本发明提供了化合物2-(4'-二苯基氨基)苯基-8-(1'-噻蒽基)-二苯并噻吩和4-(1-噻蒽基)-联(三苯基胺)。如在图1中显示的,这些化合物具有有利的物理性能,包括HOMO能级、LUMO能级和三线态能级。
在另一方面,本发明提供了空穴传输材料,其包含上述化合物或者它们与p-掺杂剂的混合物,所述p-掺杂剂是受体型有机分子。在一些实施方案中,所述掺杂剂以一定的量存在,使得当所述材料被沉积以形成层时,所述掺杂剂贡献层厚度的约10-40%,例如约33%。可以在一些实施方案以小量如基于上述化合物或混合物的重量计<50wt%的量存在在所述组合物中的其它材料包括已知的有机空穴传输剂,例如联苯或星放射状结构的芳族叔胺,在一些实施方案中为α-NPB。
在另一方面,本发明提供了光学发光二极管,其具有第一和第二电极以及在所述电极之间的、包含上述化合物或上面限定的材料的层。所述层可以是空穴传输层或空穴注入层。所述器件可以形成平板显示器或光板的一部分。其它终端用途可以包括有机光伏器件、用于形成静电潜像的成像元件、有机薄膜晶体管和染料敏化太阳能电池。
上述化合物可以被结合到其它光电或电光器件中,如下文中所述。
附图简要说明
现在将结合附图描述如何可以实施本发明,其中:
图1是沿各种定向线显示化合物α-NPB、HTS-4、HTS-8和HTS-11的空穴迁移率、熔点、玻璃化转变温度、HOMO能级和LUMO能级的点的图表;
