Efficient Organic Blue-Light-Emitting Devices with Double Confinement on Terfluorenes with Ambipolar Carrier Transport Properties

Ter(9,9‐diarylfluorene)s (TDAFs) exhibit many intriguing properties promising for blue light‐emitting devices, such as high thin‐film photoluminescence quantum yields (∼ 90 %), high glass‐transition temperatures (> 200 °C), and an unusual ambipolar carrier‐transport capability. Successful impleme...

Summary:Ter(9,9‐diarylfluorene)s (TDAFs) exhibit many intriguing properties promising for blue light‐emitting devices, such as high thin‐film photoluminescence quantum yields (∼ 90 %), high glass‐transition temperatures (> 200 °C), and an unusual ambipolar carrier‐transport capability. Successful implementation of a double‐ heterostructure device configuration that provides effective confinement of both carriers and excitons in TDAFs results in an electroluminescence performance (5.3 % external quantum efficiency) promising for application in blue‐emitting devices.
