76‐4: Late‐News‐Paper: Aromatic Hydrocarbon Macrocycles for Highly Efficient Organic Light‐Emitting Devices with Simple‐Layer Architectures

Unique and innovative devices, simple‐layer OLEDs, are currently being developed by designing multirole base materials. The multirole molecules, however, inevitably require elaborate design and multiple processes to synthesize. We show that the multirole base material for a highly efficient simple‐layer OLED can be designed with very simple aromatic hydrocarbon macrocycles.
