ADN, or 9,10-Bis(2-naphthyl)anthracene (CAS 122648-99-1), is an anthracene-based organic semiconductor supplied as a white powder. It is best known as a host material for blue OLEDs, valued for its high thermal and morphological stability.
Thanks to its wide energy band gap, ADN also works as a host in co-doped emissive layers for full colour OLEDs. In co-doping systems, a two-step energy transfer from host to dopants helps tune the emission colour and improve device performance, allowing blue, white, red and deep blue devices to be built on the same host.
ADN is offered in sublimed grade (>99.0%) and unsublimed grade (>98.0%). Sublimation is used to obtain ultra pure-grade material for device fabrication. In THF it absorbs at λ max 375,395 nm and fluoresces at λ em 425 nm, with HOMO = 5.8 eV and LUMO = 2.6 eV.
- Host material for the emissive layer of blue OLEDs.
- Host in co-doped emissive layers for full colour OLEDs, including white and red devices.
- Co-host combined with Alq3 for red-emitting electroluminescent devices.
- Host in dual emissive layer designs for deep blue OLEDs.
- Research on hole and electron transport in organic electronics.
