配位子
以下のジイリジウム錯体を、実施例12に報告された手順に従って製造することで、実施例15〜21の生成物が得られる。生成物の構造の各m/z値は、HPLC−MS測定によって検出された。
イリジウム錯体は、実施例24に従って、以下の表に示されるそれぞれの補助的な配位子を、アセチルアセトンの代わりに用いて、実施例12〜21の生成物から出発して製造される。実施例35、45及び87のイリジウム錯体の場合には、その製造は、WO2006/000544号の実施例12の手順に従って、出発材料としてそれぞれのジイリジウム錯体(実施例12〜21の生成物)から、アセトンもしくは2−ノナノン中に入れた銀トリフルオロメタンスルホネート及び以下の表に示される補助的な配位子を用いて行った。生成物の構造の各m/z値は、HPLC−MS測定によって検出された。全てのホトルミネッセンス(PL)スペクトルは、Perkin Elmer社製のLuminance Spectrometer LS50Bで測定した。材料をトルエン中に溶解させ、そして該溶液を封止されたキュベット中で窒素でパージした。溶液の励起は、PL測定を同じキュベット及び溶液を用いて実施する前に、測定された吸収特性に依存する様々な波長で行った。分光光度計は、2つの異なるランプを備え、250〜800nmの波長範囲をカバーしている。色座標CIE x,yは、PLスペクトルから測定し、分光光度計と一緒に提供されるソフトウェアによって計算した。
デバイス作製:デバイス作製の前に、ガラス上のインジウムスズ酸化物(ITO)を2mm幅のストライプとしてパターン化する(シート抵抗20Ω/平方)。基板を、アルカリ溶液(Deconex)中での超音波処理により清浄化し、脱イオン水ですすぎ、アセトン及びイソプロパノールに、各溶剤中で3〜4分間にわたり晒す。清浄化の手順の後に、基板を窒素流下で乾燥させ、引き続きUVオゾン処理を10分間行う。
