Abstract
A series of anthracene based blue host materials was synthesized and characterized with respect to their chemical, luminescence, film-forming and thermal properties. The anthracene derivatives are strongly blue fluorescent ( λ f = 435–445 nm) with high fluorescence quantum yields ( Φ f = 0.71–0.85). All of these compounds have excellent film-forming properties and thermal properties. Organic light-emitting devices (OLEDs) fabricated using these three compounds as blue host emitter and using 0.5-wt% tetra ( t-butyl) perylene (TBPe) dopant in the emitting layer exhibit good light emitting performance with bright blue emission.
