Abstract
- A spiro[benzoanthracene–fluorene] derivative containing a phenanthrene moiety, 2′,3-di(phenanthren-9-yl)spiro[benzo[de]anthracene-7,9′-fluorene] (DPSBAF), was prepared by a Suzuki coupling reaction. The photophysical and photochemical properties were investigated systematically. A non-doped organic light-emitting diode using DPSBAF as the emitter achieved a luminance efficiency of 2.18 cd A−1 with Commission Internationale de l'Éclairage 1931 chromaticity coordinates of (0.15, 0.09). The synthesized spiro[benzoanthracene–fluorene] derivative with a high thermal stability, a glass transition temperature of 210 °C and a decomposition temperature of 410 °C, shows potential for application in non-doped saturated deep-blue organic light-emitting diodes.
