Dianthranide derivative for efficient deep blue-emitting organic electroluminescence devices

摘要

We report that fluorescent organic light-emitting diodes (FOLEDs) with the emitting layer including a dianthranide derivative material produced highly efficient and bright emission in the deep blue region. It is found that this material works as an excellent host for creating high-performance FOLEDs with Commission International de L'Eclairage (CIE) coordinates (x = 0.147, y = 0.125), high current efficiency (CE) of 6.4 cd A(-1) and external quantum efficiency (EQE) of 7.40% at 20 mA cm(-2).
