摘要：
High efficiency electroluminescence (EL) in organic light emitting diodes (OLED) was achieved using cyclometallated platinum(11) complexes as new phosphorescent emitters. OLEDs containing bis[2-(2-thienyl)pyridine]platinum(II) [Pt(thpy)(2)] or bis[2-(5-trimethylsilanyl-2-thienyl)-pyridine]platinum(II) [Pt(thpy-SiMe3)(2)] show a high external EL quantum yield reaching 5.4 and 11.5% photon/electron, respectively. Both electroluminescent spectra fall in the "amber" color region defined by the automotive lighting standards; specifically the CIE coordinates are (0.58: 0.42) for Pt(thpy)(2) and (0.60; 0.39) for Pt(thpy-SiMe3)(2).
