Ir(ppy)2(bpmp), phosphorescent green emitter

High-purity (>99.5%) and available online for priority dispatch


Like Ir(ppy)3, [2-(4-methyl-5-phenyl-2-pyridinyl-κN)phenyl-κC]bis[2-(2-pyridinyl-κN)phenyl-κC] Iridium, known as Ir(ppy)2(bpmp), is a phosphorescent green emitter. It is believed that the introduction of the methyl group at para position to the pyridine nitrogen can provide a twist and electron-donating effect. This raises the LUMO energy level of the complex and the triplet energy level, resulting in a blue shift in the emission.
