摘要: 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 good thermal stability strong blue emission in solution. Typical three-layer organic devices (OLEDs) made from these show highly 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 nondoped device exhibits a maximum efficiency up 7.9 cd/A (or 6.8 lm/W). Based on the transport of anthracene-triphenylamine derivatives, deep emitting were achieved by as both emitter transporter.
