A systematic investigation to unravel the primary determinant of the operational stability of blue fluorescent organic light-emitting diodes

Abstract
The primary factor that affects the lifetime of blue FOLEDs is the bond dissociation energy (BDE) in anionic state. The BDE of host molecules has a greater impact on the lifetime than that of electron blocking layer molecules.
