Description
最近、ディスプレイの大型化に伴い空間占有の少ない平面ディスプレイの要求が増大している。かかる平面ディスプレイの一つに、有機発光ダイオード(organic light emitting diode: OLED)とも呼ばれる有機電界発光デバイスがあるが、その技術は著しく発展しつつあり、既に様々な製品が発表されている。
有機電界発光デバイスは、プラスチックのようなフレキシブルな透明基板上にもデバイスを形成できるだけでなく、プラズマディスプレイパネルや無機電界発光(EL)ディスプレイに比べて低電圧(10V以下)で駆動可能である。
従来の青色発光物質は、発光時に長波長の光が現れ、色純度と発光効率が落ちるだけでなく、ドーピング濃度が高いほど色純度と発光効率がより低下するという問題があった。
本発明は上記のような問題を解決するためのもので、青色の色純度と発光効率に優れた有機電界発光デバイスを提供することが目的である。

本発明は基板上に形成される第1、第2電極の間に発光層が形成され、発光層は複数の物質で形成され、下記の化学式1をドーパントに使用する青色発光物質からなる。

(1) 1,6-Dibromopyreneの合成
次いで、底の丸いフラスコに設置されたドロッピングファンネル(dropping funnel)に Br2(17.38g, 0.108mol)とCCl4(50mL)を入れた後、これを底の丸いフラスコで4時間ゆっくり滴下させる。そして、その溶液にN2を注入し、発生するHBrを除去する。
このようなドロッピング過程が終わると、約1時間その溶液をN2気流下で攪拌させた後、生成された沈殿物をフィルタリングする。
そして、沈殿物をトルエンを使用して再結晶させると、1,6-ダイブロモピレン(1,6-Dibromopyrene)の緑色の固体(6.05g, 34%)と、1,8-ダイブロモピレン(1,8-Dibromopyrene)(5g, 28%)の白色の固体とが得られる。
そして、反応終結時に2首の底の丸いフラスコを常温で冷却し、反応溶媒のトルエン40mLを減圧蒸留して除去する。
そして、反応終結時に、水とダイエチルエテル(diethylether)を使用して結果物を抽出し、MgSO4を使用して結果物から水を除去する。
そして、反応終結時に、底の丸いフラスコを冷却し、反応溶液のトルエンを除去する。
そして、反応終結時に、底の丸いフラスコを冷却し、反応溶媒のトルエンを除去した後、水とメチレンクロライドを使用して結果物を抽出する。
この固体でトルエンを約50%程度除去した後、メタノール(70mL)を添加してフィルタリングする。
ITO基板(glass)の発光面積が3mm×3mmの大きさとなるようにパタニングした後洗浄した。
