    • The present invention provides electronic devices comprising novel polymeric organic iridium compositions which provide for enhanced device performance. The polymeric organic iridium compositions employed comprise a polymeric organic iridium compound comprising at least one cyclometallated ligand and at least one ketopyrrole ligand. The polymeric organic iridium compositions employed are referred to as Type (2) organic iridium compositions and are constituted such that at least one ligand of the polymeric organic iridium compound has a number average molecular weight of 2,000 grams per mole or greater (as measured by gel permeation chromatography). Type (2) organic iridium compositions are referred to herein as comprising “polymeric organic iridium complexes”. In one aspect, the present invention provides optoelectronic devices, such as OLED devices and photovoltaic devices. In another aspect, the invention provides OLED devices exhibiting enhanced color properties and light output efficiencies.
    • 本发明提供了包含新型聚合物有机铱组合物的电子器件,其提供增强的器件性能。 所用的聚合有机铱组合物包括含有至少一个环金属配体和至少一个酮基吡咯配体的聚合有机铱化合物。 所使用的聚合有机铱组合物称为类型(2)有机铱组合物,并且构成为使得聚合有机铱化合物的至少一种配体的数均分子量为每摩尔或更大2000克(通过凝胶测量) 渗透色谱)。 类型(2)有机铱组合物在本文中被称为包含“聚合有机铱络合物”。 在一个方面,本发明提供了诸如OLED器件和光伏器件之类的光电器件。 在另一方面,本发明提供具有增强的颜色特性和光输出效率的OLED器件。
