New asymmetrically highly twisted anthracene derivatives serve as a matched host and guest material in high efficiency blue OLEDs. 2-(2-Methylnaphtathalene-1-yl)-9, 10-di (naphthalene-2-yl) anthracene and N-(4-(10-naphthalene-2-yl) anthracene-9-yl) phenyl-N- phenylnaphthalene-2-amine were prepared as host material and as guest material, respectively. Multilayer organic electroluminecent devices constructed using these ...
