*Sublimation is a technique used to obtain ultra pure grade chemicals to get rid of mainly trace metals and inorganic impurities. Sublimation happens under certain pressure for chemicals to only go through two physical stages, from a solid sate to vapour (gas) and then the vapour condensed to a solid state on a cool surface (referred to as cold finger). The most typical examples of sublimation are iodine and dry ice. For more details about sublimation, please refer to sublimed materials for OLEDs and perovskites and our collection of sublimed materials.
ApplicationsLike 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 also electron donating effect, raising the LUMO energy level of the complex and also the triplet energy level, resulting a blue shift in the emission.
