　　Blue light-emitting anthracene derivatives end-capped with triphenylamine for efficient hole transportation have been designed and synthesized using two-step Suzuki coupling reactions.The compounds possess high glass transition temperatures for good thermal stability,and strong blue emission in solution.Typical three-layer organic light-emitting devices (OLEDs) made from these compounds show highly-efficient blue emission,which are better than or comparable to state-of-the-art fluorescent OLEDs performance.For example,9-pyrenyl-10-(4-triphenylamine) anthrancene (PAA)-based non-doped device exhibits efficient blue emission with a maximum efficiency up to 7.9 cd/ A (or 6.8 lm/W).Based on the good hole transport of the anthracene-triphenylanmine derivatives,deep blue emitting devices with high efficiency were achieved by using the derivatives as both emitter and hole-transporter.
