Abstract
The present invention provides electronic devices comprising novel organic iridium compositions which provide for enhanced device performance. The novel iridium compositions employed comprise at least one novel organic iridium compound which comprises at least one cyclometallated ligand and at least one ketopyrrole ligand. The organic iridium compositions employed are referred to as Type (1) organic iridium compositions and are constituted such that no ligand of the novel organic iridium compound has a number average molecular weight of 2,000 grams per mole or greater (as measured by gel permeation chromatography). Type (1) organic iridium compositions are referred to herein as comprising '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.
