ADN - 9,10-Bis(2-naphthyl)anthrace

ADN, a promising host material for full colour OLEDs

High thermal and morphological stability. Available online for priority dispatch

---

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.
