MADN, 2-methyl-9,10-bis(naphthalen-2-yl)anthracene is commonly known as a blue emitter. It is widely used as a highly-efficient blue host material and hole-transporting material (HTM) for organic electronic devices. Exhibiting an ambipolar transporting ability, MADN offers stable thin-film morphology and a wide energy band-gap.
As a hole-transporting material, MADN can reduce the amount of hole carriers injected into the device - leading to a well-balanced carrier recombination .
