Abstract
Description
有機発光デバイスを提供する。
Mは40より大きな原子量を有する金属であり;
(C−N)は置換又は非置換シクロメタル化配位子であり、(C−N)は金属に結合された少なくとも1の他の配位子とは異なり;
それぞれのRは独立して、水素、アルキル、アルケニル、アルキニル、アルキルアリール、CN、CF3、CO2R、C(O)R、NR2、NO2、OR、ハロゲン、アリール、ヘテロアリール、置換アリール、置換ヘテロアリール、又はヘテロ環式基、から選択され;
加えて又はそれに代えて、任意選択された2つの隣接置換位置は一緒になって、独立して縮合4〜7員環式基を形成し、前記環式基はシクロアルキル、シクロヘテロアルキル、アリール、又はヘテロアリールであり、さらに前記4〜7員環式基は場合によっては置換基Rで置換されていることができ;
mは少なくとも1の値を有し;
nは少なくとも1の値を有し;nが3である場合、Rはシアノ基ではなく;
m+nは、上記金属に結合しうる配位子の最大数である。
一般に、OLEDは、アノード及びカソードの間に配置され且つこれらと電気的に接続された少なくとも1つの有機層を含む。本明細書で用いるように、「の間に配置され且つこれらと電気的に接続された」とは、言及した層が隣接し且つ直接接触していることをいうものではない。むしろ、言及した層の間に追加の層が配置されることを許容する。電流が流れると、アノードは正孔を(1以上の)有機層中に注入し、カソードは(1以上の)有機層中に電子を注入する。注入された正孔及び電子は、それぞれ反対に帯電した電極に向かって移動する。電子及び正孔が同一分子上に局在した場合、励起エネルギー状態を有する局在化した電子−正孔対である「励起子(エキシトン)」が形成される。この励起子が発光機構を通って減衰するときに光が放射される。いくつかの場合には、励起子は励起分子(エキシマー)又は励起錯体(エキシプレックス)上に局在することもできる。無放射機構、例えば熱減衰もまた生じうるが、通常は好ましくないと考えられる。
Mは40より大きな原子量を有する金属であり;
(C−N)は置換又は非置換シクロメタル化配位子であり、(C−N)は金属に結合された少なくとも1の他の配位子とは異なり;
それぞれのRは独立して、水素、アルキル、アルケニル、アルキニル、アルキルアリール、CN、CF3、CO2R、C(O)R、NR2、NO2、OR、ハロゲン、アリール、ヘテロアリール、置換アリール、置換ヘテロアリール、又はヘテロ環式基、から選択され;
加えて又はそれに代えて、任意選択された2つの隣接置換位置は一緒になって、独立して縮合4〜7員環式基を形成し、前記環式基はシクロアルキル、シクロヘテロアルキル、アリール、又はヘテロアリールであり、さらに前記4〜7員環式基は場合によっては置換基Rで置換されていることができ;
mは少なくとも1の値を有し;
nは少なくとも1の値を有し;かつ、
m+nは、上記金属に結合しうる配位子の最大数である。
本発明の合成された錯体については、メリジオナル異性体(meridional isomers)とフェーシャル異性体(facial isomers)は同様に振る舞うことが観測されている。したがって、位置異性体の選択は、デバイス性能に大きな影響を及ぼさないと考えられる。メリジオナル異性体は、より容易に合成されることが発見されていることから好ましい。例えば、フェーシャル異性体は一般にメリジオナル異性体を変換することによって合成される。フェーシャル異性体は、有機金属化合物において現在最も一般的異性体であることから好ましいものでありうる。
