Abstract: In this article, an all solution-processed blue organic light-emitting diode (OLED) comprising the emissive fluorene/dibenzothiophene-S,S-dioxide co-oligomer, 3,7-bis[7-(9,9-di-n-hexylfluorenyl-2,7-diyl)-9,9-di-n-hexylfluoren-2-yl]-dibenzothiophene-S,S-dioxide (HFSO), and a poly-ethyleneimine (PEI)/ultrafine-ZnO-nanoparticle (NP) bilayer in the conventional device structure is proposed for the first time.… read more here.
