제목 Thermally cross-linkable hole transport material for blue phosphorescent organic light-emitting diodes.
초록 A high triplet energy crosslinkable hole transport material was developed as the hole transport material for solution processed blue phosphorescent organic light-emitting diodes. A high triplet energy core structure was functionalized with a styrene crosslinking unit to form the crosslinked hole transport layer. Crosslinking of the hole transport layer at 220 oC produced an insoluble film which is stable under exposure to various solvents. A blue emitting layer of synthesized material was spin-coated on the cross-linkable hole transport layer without damaging the underlying hole transport layer, which afforded solution processed blue phosphorescent organic light-emitting diodes with an external quantum efficiency of 19.07%.
