Description
1)化合物(C)の製造
シクロ−1,4−ジオン(A)30g(267.5mmol)を2Lフラスコに入れ、アセト酸900mlを加えた。前記混合物にフェニルヒドラジン(B)2.2当量57.9ml(588.6mmol)を徐々に滴加して反応混合物をTLCで観察し、シクロ−1,4−ジオンが全て消えたことを確認した後、5℃まで冷却した。冷却後、濃硫酸10当量142ml(2.6754mol)を徐々に滴加し、全て滴加した後、反応混合物の温度を80℃まで上昇させて1時間反応させた。
2Lフラスコに化合物(C)22.8g(89mmol)、N−メチルピロリジノン約1.2Lを付加した後で、反応混合物の温度を30℃まで上げた。次に、前記反応混合物にN−ブロモスクシンイミド(NBS)33.3g(186.8mmol)を徐々に滴加し、これを2時間程度撹拌した。
化合物(D)10g(24.1mmol)、炭酸カルシウム3.25g(57.84mmol)及びブロモオクタン11.17g(57.84mmol、1.2Eqiv.)をジメチルホルムアミド150mLに溶解させた後、150℃に上げ、この温度で約16時間還流させた。
2,7−ジブロモフルオレン25g(77mmol)とオクチルブロマイド36g(185mmol)をトルエン100mlに溶解させ、ここにTBAB(テトラブチルアンモニウムブロマイド)1.25g(3.85mmol)を添加した。前記混合物にNaOH31g(770mmol)を水50mlに溶解させた水酸化ナトリウム水溶液を添加した後、これを2日間還流させた。
フラスコ内部を数回真空化及び窒素還流させて水分を完全に除去し、ビス1,5−シクロオクタジエンニッケル(Ni(COD))880mg(3.2mmol)とバイピリダル(bipyridal)500mg(3.2mmol)をグローブボックス内に投入し、再び数回フラスコ内部を真空化及び窒素還流させた。次に、窒素ガス雰囲気下で無水ジメチルホルムアミド(DMF)10mlと1,5−シクロオクタジエン(COD)346mg(3.2mmol)及び無水トルエン10mlを添加した。前記反応混合物を80℃で30分間撹拌させた後、前記合成例1から得た化合物(E)102mg(0.16mmol)と前記合成例2から収得した化合物(F)790mg(1.44mmol)とをトルエン10mlに希釈した溶液を添加した。その後、前記反応混合物にトルエン10mlを添加しつつフラスコ器壁についている物質を全て洗った後、これを80℃で4日間撹拌させた。4日経過後、ブロモペンタフルオロベンゼン1mlを添加して80℃で一日ほどさらに撹拌させた。
フラスコ内部を数回真空化、窒素還流させて水分を完全に除去した後、前記フラスコにNi(COD)880mg(3.2mmol)とバイピリダル500mg(3.2mmol)をグローブボックス内に投入した後、再び数回フラスコ内部を真空化、窒素還流させた。次に、窒素気流下で無水DMF 10mlとCOD 346mg(3.2mmol)及び無水トルエン10mlを添加した。前記反応混合物を80℃で30分間撹拌した後、前記合成例2から収得した化合物(F)、すなわち9,9’−ジオクチル−2,7−ジブロモフルオレン1.03g(1.28mmol)をトルエン10mlに希釈して添加した。その後、器壁についている物質をいずれも洗いつつトルエン10mlを添加した後、80℃で4日間撹拌した。4日経過後、ブロモペンタフルオロベンゼン1mlを添加して80℃で一日ほど撹拌させた。
ITOがコーティングされた透明電極基板をきれいに洗浄した後、ITOを感光性樹脂とエッチング剤を利用してパターニングしてITO電極パターンを形成し、これを再びきれいに洗浄した。このように洗浄された結果物上にPEDOT(Batron P4083(Bayer社))を約500の厚さにコーティングした後、180℃で約1時間ベーキングしてホール注入層を形成した。
前記発光層形成用の組成物製造時、前記合成例3によって製造されたポリ(ジオクチルフルオレン−コ−インドロカルバゾール)の代わりに前記比較合成例1によって製造されたポリ(9,9’−ジオクチル−2,7−フルオレン)を使用したことを除いては、実施例1と同じ方法によって実施して有機EL素子を製作した。
