Aryl‐substituted asymmetric anthracene blue host materials, 10‐naphthalene‐2‐yl‐9‐phenyl‐2‐triphenylsilylanthracene ( 6 ) and 9‐(4‐( tert ‐butyl)phenyl)‐10‐(2‐methyl‐5‐(naphthalen‐1‐yl)phenyl)anthracene ( 7 ) were synthesized and characterized. Asymmetric anthracene derivatives 6 and 7 possessed high thermal stabilities that are suitable as emitting layer materials for blue organic light‐emitting device. The electroluminescence emission maximum of BD ‐142‐doped (7 wt %) two devices exhibited at 464 nm (for 6 ) and 472 nm (for 7 ), respectively. All devices showed good performances as blue host materials. The 7 ‐based device especially displayed higher device performances in terms of brightness ( L max = 37 090 cd/m 2 ), luminous current density (7.26 cd/A), and external quantum efficiencies (5.80%) than those of 6 ‐based device.
