*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.
9,10-Bis(2-naphthyl)anthracene (ADN), which is well known for its high thermal and morphological stability, is widely used as the host material for blue OLEDs [1, 2].
However, with the development of the co-doping technology*, 9,10-Bis(2-naphthyl)anthrace has also shown to be a promising host material for full colour OLEDs due to its wide energy band gap [3, 4, 5].
*The co-doping system is a novel technique for colour tuning and increasing the emission characteristics of OLEDs, and the two-step energy transfer in this system plays a very important role in colour tuning and improvement of the device performance.
