Description
本発明は、下記構造Iの化学構造を有する有機金属錯体の調製と有機発光デバイス(OLED)での応用に関する。
R6〜R15は独立に、水素、アルキル、置換アルキル、シクロアルキル、アリール、及び置換アリール基であり;
R16〜R23は独立に、炭素、窒素、酸素、ケイ素、リン、硫黄、ヒ素、及びセレンであり;
Z1〜Z8は独立に、水素、アルキル、置換アルキル、シクロアルキル、アリール、置換アリール基であり、Z1〜Z8は隣接基と5〜7員環を形成してもよい。本発明は、そのような錯体を作るために有用な配位子も提供する。
構造Iの化学構造をもつ有機金属錯体はシクロメタル化錯体といわれる。構造I中の白金中心(上を参照されたい)は+2の酸化状態であり、平面四角形の幾何構造を有する。
