窒素雰囲気下で、化学式2の[Ir(F2ppy)2Cl]2BDP 0.1mmolをメチレンクロライド10mLに溶解した後、ここにメタノール15mLに溶解されたKCN 10mmol溶液を添加した。前記反応混合物を常温で5時間撹拌させた後、これより溶媒を減圧蒸留して除去した。次いで、反応結果物を9:1:3混合体積比のメチレンクロライド、アセトン、へキサンよりなる混合溶媒を使用して、シリカゲルカラムを通過させて分離した。実施例1の方法を用いて、それぞれのカラム通過物から沈殿物を得た。シリカゲルカラムを通じて最初に溶離された物質は、未反応の[Ir(F2ppy)2Cl]2BDPであり、2番目に溶離された物質は、化学式4の[Ir(F2ppy)2Cl]−BDP−[Ir(F2ppy)2CN]であり、3番目に溶離された物質は、化学式3の[Ir(F2ppy)2CN]2BDPであった。これらの分子構造式及び組成は質量分析器と1H NMRスペクトルを使用して分析及び確認した。
窒素雰囲気下で、下記構造式で表される[Ir(F2ppy)2Cl]20.1mmolをメチレンクロライド10mLに溶解した後、ここに、下記構造式で表されるP(Ph)2(CH2)2P(Ph)(CH2)2P(Ph)2(3P)0.1mmolを添加した。
前記実施例1の方法と類似した方法によって、P(Ph)2(CH2)3P(Ph)2を反応させて化学式6で表される化合物を合成した。
前記実施例1の方法と、実質的に同一の方法によって、P(Ph)2(CH2)2P(Ph)2を反応させて化学式7で表される化合物を合成した。
また、前記化学式7の化合物の分子量はESI質量スペクトルを通じて確認した。
前記実施例1の方法と類似した方法とによってP(cyclohexyl)2(CH2)2P(cyclohexyl)2を反応させて化学式8で表される化合物を合成した。
また、前記化学式8の化合物の分子量はESI質量スペクトルを通じて確認した。
前記実施例1の方法と類似した方法とによってP(Ph)2(CH2)2O(CH2)2P(Ph)2を反応させて化学式9で表される化合物を合成した。
前記実施例1の方法と実質的に同一の方法によって、P(Ph)2(Ph)2P(Ph)2を反応させて化学式10で表される化合物を合成した。
前記実施例1の方法と、実質的に同一の方法によってP(cyclohexyl)2(Ph)2N(CH3)2を反応させて、化学式11で表される化合物を合成した。
PEDOTのイソプロピルアルコール溶液を、あらかじめ洗浄されたITOコーティングされているガラス基板上にスピンコーティングし、これを120゜Cで1時間ベイクしてホール注入及びホール輸送層を形成した。次いで、PMMA及びmCPにドーパント6%がドープされたフィルムを得るために、0.015g、mCP 0.0226g及びドーパント[(F2ppy)IrCN]2BDP 0.0025gをジクロロエタン 3.96gに溶解して溶液を得た。前記PMMA及びmCPの混合比は40:60であった。
