Abstract
本發明提供一種驅動電壓、效率及壽命得到改良的有機發光裝置。
Description
[相關申請案的交叉參考] 本申請案主張於2016年9月6日在韓國智慧財產局提出申請的韓國專利申請案第10-2016-0114284號的權利,所述韓國專利申請案的揭露內容全文併入本案供參考。
本發明是有關於一種驅動電壓、效率及壽命得到改良的有機發光裝置。
一般而言,有機發光現像是指使用有機材料將電能轉換成光能的現象。利用有機發光現象的有機發光裝置具有例如視角寬、對比度優異、響應時間快、亮度、驅動電壓及響應速度優異等特性,且因此已進行了諸多研究。
有機發光裝置一般具有包括陽極、陰極以及夾置於所述陽極與所述陰極之間的有機材料層的結構。有機材料層常常具有包含不同材料的多層式結構以增強有機發光裝置的效率及穩定性,且舉例而言,有機材料層可由電洞注入層、電洞傳輸層、發光層、電子傳輸層、電子注入層等形成。在有機發光裝置的結構中,若在兩個電極之間施加電壓,則電洞會自陽極注入至有機材料層且電子會自陰極注入至有機材料層,且當所注入的電洞與電子彼此相遇時,形成激子(exciton),並且當所述激子再次落至基態時發出光。
在有機發光裝置領域中,持續需要開發一種驅動電壓、效率、及壽命得到改良的有機發光裝置。

根據本發明的有機發光裝置的特徵在於,所述有機發光裝置可藉由對包含於電洞傳輸層及發光層中的材料進行控制來控制各層之間的能級,從而改良驅動電壓、效率及壽命。
以下,將針對每一組件詳細地闡述本發明。第一電極及第二電極
本發明中所述的第一電極及第二電極是用於有機發光裝置中的電極。舉例而言,第一電極是陽極且第二電極是陰極,抑或第一電極是陰極且第二電極是陽極。
作為陽極材料,一般而言,較佳地使用具有大的功函數的材料以使得可將電洞平穩地注入至有機材料層中。陽極材料的具體實例包括:金屬,例如釩、鉻、銅、鋅及金、或其合金;金屬氧化物,例如氧化鋅、氧化銦、氧化銦錫(indium tin oxide,ITO)及氧化銦鋅(indium zinc oxide,IZO);金屬與氧化物的組合,例如ZnO:Al或SnO2
:Sb;導電聚合物,例如聚(3-甲基噻吩)、聚[3,4-(乙烯-1,2-二氧基)噻吩](poly[3,4-(ethylene-1,2-dioxy)thiophene],PEDOT)、聚吡咯及聚苯胺等,但並非僅限於此。
作為陰極材料,一般而言,較佳地使用具有小的功函數的材料以使得可將電子輕易地注入至有機材料層中。陰極材料的具體實例包括:金屬,例如鎂、鈣、鈉、鉀、鈦、銦、釔、鋰、釓、鋁、銀、錫及鉛,或其合金;多層式結構材料,例如LiF/Al或LiO2
/Al等,但並非僅限於此。
此外,在陽極上可更包括電洞注入層。電洞注入層是由電洞注入材料製成,且電洞注入材料較佳為以下化合物:所述化合物具有傳輸電洞的能力、在陽極中具有電洞注入效果及對發光層或發光材料具有優異的電洞注入效果,防止在發光層中產生的激子移動至電子注入層或電子注入材料,且具有優異的薄膜形成能力。
較佳地,電洞注入材料的最高佔用分子軌域(highest occupied molecular orbital,HOMO)處於陽極材料的功函數與外圍有機材料層的最高佔用分子軌域之間。電洞注入材料的具體實例包括金屬卟啉(porphyrin)、寡聚噻吩、芳胺系有機材料、六腈六氮雜苯並菲系有機材料、喹吖啶酮(quinacridone)系有機材料、苝(perylene)系有機材料、蒽醌、聚苯胺及聚噻吩系導電聚合物等,但並非僅限於此。
另外,在第一電極與電洞傳輸層之間及/或在第二電極與電子傳輸層之間,可更包括有機層。所述有機層亦包括發光層。電洞傳輸 層、第一發光層、第二發光層
本發明的電洞傳輸層是自形成於陽極中或陽極上的電洞注入層接收電洞且將電洞傳輸至發光層的層。對於電洞傳輸材料,適宜為可自陽極或電洞注入層接收電洞且將電洞傳輸至發光層的材料、具有大的電洞遷移率的材料。
具體而言,在本發明的有機發光裝置中,較佳地電洞傳輸層與第一發光層彼此接觸,且使用與包含於第一發光層中的1-1主體相同的材料作為電洞傳輸材料。
當如在本發明的有機發光裝置中般設置多個發光層時,位於陽極側上的第一發光層充當用於將電洞注入至第二發光層的電洞傳輸層。為了將電洞移動至第二發光層,應無任何損耗地傳輸來自陽極的電洞。為此,較佳地,構成第一發光層的主體的材料中的一種材料是由與包含於電洞傳輸層中的材料相同的材料製成。在此種情形中,電洞傳輸層與第一發光層之間的介面電阻(interface resistance)可減小,電洞可更容易引入至第一發光層,且傳輸至第二發光層的電洞的量可增加,藉此一般會提高有機發光裝置的發光效率且防止驅動電壓增大。此外,藉由使用具有優異電洞傳輸性質的材料作為第一發光層的主體中的一者,第一發光層自身的電洞傳輸性質可得以改良。此外,由於第一發光層的摻雜劑提供足以用於執行電洞陷阱(hole trap)的電洞量,因此可提供用於提高第一發光層及第二發光層中的發光效率所必需的足夠的電洞。
作為電洞傳輸材料及1-1主體,可使用由以下化學式1表示的化合物: [化學式1]在化學式1中, R1

如上所述,由於第一發光層包含與電洞傳輸層相同的材料,因此可將電洞充分地供應至第一發光層。然而,為了提高有機發光裝置的總體發光效率,電子應容易穿過第二發光層進入第一發光層。為此,藉由包含與第二發光層的主體相同而與第一發光層的電洞傳輸層不同的材料,可適當地調整第一發光層中的電子與電洞之間的均衡(balance)以提高發光效率。另外,當將電子自第二發光層注入至第一發光層時,電子會移動穿過同一種材料,因而使得第一發光層與第二發光層之間的介面電阻減小且可降低驅動電壓。
作為1-2主體,可使用由以下化學式2表示的化合物: [化學式2]在化學式2中, Ar5
與Ar6

在第二發光層周圍,第一發光層應具有注入電洞的作用,而第三發光層應具有注入電子的作用。如上所述,第一發光層包含與包含於電洞傳輸層中的具有優異電洞傳輸性的材料相同的材料。另外,由於第一發光層距陰極最遠,因此較佳地第三發光層包含與第二發光層相同的材料以平穩地提供電子。由於第二發光層較第一發光層更靠近陰極,因此勢必會良好地傳輸電子,但可藉由包含具有雙極(bipolar)特性的材料來調整電荷均衡(charge balance)以提高效率。此外,由於在二或更多個發光層中包含同一種材料,因此亦存在藉由減小各發光層之間的介面電阻而降低驅動電壓的效果。
