  Phosphorescent iridium complex with non-conjugated cyclometalated ligands, synthetic method of preparing the same and phosphorescent organic light emitting diode thereof

  摘要：

  本发明披露了一种荧光三螯合过渡金属配合物，包括i)两个相同的非共轭环金属配体与过渡金属形成配位球，并将一个配位色团并入配位球中；或ii)一个非共轭环金属配体与过渡金属形成配位球，并将两个配位色团并入配位球中。其中金属为铱、铂、锇或钌，配位色团与非共轭环金属配体相比具有较低的能隙，后者提供了有效的屏障以抑制配体间的电荷转移过程，从而使这些过渡金属配合物的激发态的辐射衰减限制在单个配位色团中。配位色团的结构和能隙适合于产生高效的蓝色、绿色甚至红色发射。

  The present invention discloses a phosphorescent tris-chelated transition metal complex comprising i) two identical non-conjugated cyclometalated ligands being incorporated into a coordination sphere thereof with a transition metal, and one ligated chromophore being incorporated into the coordination sphere; or ii) one non-conjugated cyclometalated ligand forming a coordination sphere thereof with a transition metal, and two ligated chromophores being incorporated into the coordination sphere, wherein the metal is iridium, platinum, osmium or ruthenium, and the ligated chromophore possesses a relatively lower energy gap in comparison with that of the non-conjugated cyclometalated ligand, the latter afforded an effective barrier for inhibiting the ligand-to-ligand charge transfer process, so that a subsequent radiative decay from an excited state of these transition complexes will be confined to the single ligated chromophore. The architecture and energy gap of the ligated chromophore are suitable for generation of high efficiency blue, green and even red emissions.
