Highly fluorescent solid-state benzothiadiazole derivatives as saturated red emitters for efficient solution-processed non-doped electroluminescent devices

Article abstract of DOI:10.1039/d0tc02131h

Four donor-π-acceptor type saturated red emitters, namely BTZn, employing two isomeric bis(n-hexylthiophen-2-yl)-benzothiadiazoles as the π-acceptor core and a triphenylamine donor as multiple substituents, were designed and synthesized. The highly twiste

Graphical Abstract
Highly fluorescent solid-state benzothiadiazole derivatives as saturated red
emitters for efficient solution-processed non-doped electroluminescent devices

Terdkait Kaewpuang, Thanaporn Manyum, Supawadee Namuangruk and Vinich Promarak*
Benzothiadiazole derivatives bearing multiple triphenylamine substituents exhibit a strong solid-state
red fluorescence emission with bipolar transporting properties. Simple structured solution processed
non-doped devices emit brilliant saturated red emission peaked at 648 nm with maximum luminance
of 6842 cd m-2, EQE as high as 4.15% and low turn on voltage of 3.3 V.
