Description
本發明關於一種有機金屬化合物及包含其之有機電激發光裝置,特別關於一種有機金屬磷光化合物及包含其之磷光有機電激發光裝置。
有機電致發光裝置(organic electroluminescent device),亦稱作有機發光二極體(organic light-emitting diode;OLED),是以有機層作為主動層的一種發光二極體(LED)。由於有機電致發光裝置具有低電壓操作、高亮度、重量輕、廣視角、以及高對比值等優點,近年來已漸漸使用於平面面板顯示器(flat panel display)上。與液晶顯示器不同,有機電激發光顯示器所包含之有機發光二極體畫素陣列係具有自發光的特性,因此不需外加背光源。
一般而言,有機發光二極體元件包括一對電極,以及在電極之間的一有機發光介質層。發光是導因於以下的現象。當電場施於兩電極時,陰極射出電子到有機發光介質層,陽極射出電洞到有機發光介質層。當電子與電洞在有機發光介質層內結合時,會產生激子(excitons)。電子和電洞的再結合就伴隨著發光。
依據電洞和電子的自旋態(spin state),由電洞和電子之再結合而產生的激子可具有三重態(triplet)或單重態(singlet)之自旋態。由單重態激子(singlet exciton)所產生的發光為螢光(fluorescence),而由三重態激子(triplet exciton)所產生的發光為磷光(phosphorescence)。磷光的發光效率是螢光的三倍。因此,發展高效率的磷光材料以增進有機發光二極體元件的發光效率是非常重要的。
目前有機發光二極體元件發光單元材料以小分子材料為主,這是因為小分子有機發光二極體元件不管在效率、亮度與壽命等均較高分子有機發光二極體元件(PLED)高出許多。現今小分子有機發光二極體元件製程不像PLED以旋轉塗佈或是噴墨印刷(Inkjet printing)為主,而是以蒸鍍方式為主。然而,用於蒸鍍方式所使用之真空製程設備成本較高,此外只有5%的有機發光材料會鍍在基板上,95%的有機發光材料浪費在腔體壁上,使得有機發光二極體元件的製造成本居高不下。因此,濕式製程(包含旋轉塗佈(spin coating)、或刮刀塗佈(blade coating))被提出用於小分子有機發光二極體元件的製程上,來降低設備成本及大大提升有機發光材料的使用率。
不過,傳統有機磷光發光材料由於溶解度差的關係,並不適合濕式製程。因此,開發出適用於濕式製程的可溶性有機磷光發光材料是最為關鍵的材料(尤其是作為橘黃光摻雜劑),對於有機發光二極體技術而,是一個很重要的課題。
本發明提出一種有機金屬化合物,係將烷基或環烷基導入4-phenylthieno[3,2-c]pyridine結構,使材料具有好的溶解度。本發明所述之有機金屬化合物,可應用在有機電激發光裝置,作為發光單元的材料,提升有機電激發光裝置的元件效率。
根據本發明一較佳實施例,該有機金屬化合物,具有如式(I)所示之化學結構:
其中,A1
係二異丙基碳二亞胺(diisopropyl carbodiimide)配位基、5-(2-吡啶)-1,2,4-三唑(5-(2-pyridyl)-1,2,4-triazole))配位基、具有苯環之乙醯丙酮(acetylacetone)配位基、2-苯環-1,3,4-噁二唑配位基(2-phenyl-1,3,4-oxadiazole)、或其衍生物。
根據本發明另一較佳實施例,本發明係提供一種有機電激發光裝置,該裝置包含一對電極;以及一有機發光單元,配置於該對電極之間,其中該有機發光單元包含上述之有機金屬化合物,可作為橘紅光、或紅光磷光摻雜材料。
