摘要：

A 2,7-functionalized pyrene-based emitter for highly efficient OLEDs has been developed. The chromophore can be prepared on a large scale in good yields. It offers an exceptional deep blue photoluminescence (CIE: x = 0.16, y = 0.024) and good external quantum efficiency (EQE) of 3.1% when employed in a guest-host system OLED.
