TBADN, blue fluorescent emitter for non-doped OLEDs

Can be solution processed to achieve an amorphous solid-state film


TBADN, or 2-tert-Butyl-9,10-di(naphth-2-yl)anthracene, is commonly used as a blue emitter in organic light emitting devices. With a bulky t-butyl group at the 2-position of anthracene, the non-planar molecular structure of TBADN can prevent the unfavourable packing of the emitting material with the hole transporting material at the interface.

TBADN used as a blue fluorescent emitter in a non-doped organic light-emitting diode has shown efficient blue emission color purity with excellent Commission International de L’Eclairage (CIE) coordinates (x = 0.14, y = 0.10). TBADN is also used as host material for blue dopant materials such as DPAVBi. With its increased solubility compared to ADN, TBADN can also be solution processed and an amorphous solid-state film can be achieved.
