Efficient Non-Doped Blue Electroluminescence Based on Phenanthroimidazole–Benzoylfluorene Hybrid Molecules with High Spin-Orbit Coupling and Balanced Charge Mobilities

Developing non-doped blue organic light-emitting diodes (OLEDs) with excellent photoluminescence quantum yield (PLQY), high exciton utilization efficiency (EUE) and balanced carrier mobility is an urgent challenge. Herein, two blue molecules...
