Isomeric Separations of Cyclometalated Iridium (III) Complexes Using the ACQUITY UPC2 System

چکیده
IN T RODUC T ION Synthesis and characterization of cyclometalated iridium (III) complexes in organic light emitting display (OLED) applications is of great interest, as these complexes display high emission quantum yields and can be readily colortuned through systematic modification of the ligands using facile syntheses. Depending on the types of ligands surrounding the central iridium atom, these organometallic complexes can be categorized as homoand heteroleptic. Both homoand heteroleptic complexes can exist as geometric isomers often referred to as meridional (mer) and facial (fac) isomers. Geometric isomers display vastly different photophysical and chemical properties, which can affect the performance and lifetime stability of OLED devices. In addition, heteroleptic complexes possess optical isomerism. Enantio-enriched complexes emit circularly polarized light and can be used for three-dimensional electronic displays.
