Patent number: 7718277Abstract: 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.Type: GrantFiled: August 16, 2006Date of Patent: May 18, 2010Assignee: General Electric CompanyInventors: Kelly Scott Chichak, James Anthony Cella, Kyle Erik Litz, Joseph John Shiang, Qing Ye
