Abstract

Abstract: The current trend for fabricating OLEDs is solution processing in the scope for low-cost manufacturing, but most small organic molecules must be deposited in vacuum to fabricate devices due to their poor solubility. In this paper, a new soluble anthracene derivative 2-tert-butyl-9,10-bis(9,9-dipropylfluorenyl)anthracene(TBPFA) was designed and synthesized. The compound exhibited pure-blue-light emitting(λ_max=443 nm in dilute dichloromethane, λ_max=450 nm in solid film) and high fluorescence quantum efficiency. The none-doped and doped single-layer devices were prepared successfully by spin coating process with TBPFA as blue-light emitting material and blue-light emitting host material respectively. In the doped device, TBPFA can transport energies to TBPe which is a good blue-light emitting material efficiently.

Key words: OLEDs, Solution process, Blue-light emitting host material, Anthracene derivative
