Abstract:Thermally activated delayed fluorescence (TADF) assisted fluorescence organic light‐emitting devices (TAF‐OLEDs), also known as hyperfluorescence OLEDs, sometimes have limited operational lifetimes, making them unsuitable for industrial applications. Although, this limitation is believed to originate from the irreversible degradation of constituent materials, the chemical processes underlying this degradation remain elusive. This study enables to better understand the chemical origins of the degradation proces… Show more
