Abstract

In this work, a blue emitter with a 3D rigid structure composed of multiple spirobifluorene (3-Spiro) has been synthesized and characterized. Through a detailed study of the electrochemical and photophysical properties of 3-Spiro, we have evidenced that 3-Spiro can be applied as an active component of organic light-emitting diodes (OLEDs). The device with 5% doping rate of 4CzPNPh exhibits high external quantum efficiency (EQE) of 11%, which proves the potential of 3D rigid structure emitters for OLEDs.
