Synthesis and device performance of high triplet energy electron transport type exciton blocking materials for stable blue phosphorescent organic light-emitting diodes |
초록 |
High triplet energy electron transport materials with dibenzothiophene and dibenzofuran core modified with a diphenyltriazine unit were developed. The two exciton blocking materials showed high triplet energy above 2.80 eV by stable aromatic units in molecular structure. Small dihedral angle between aromatic moieties allowed them to maintain the lifetime of the reference device without the exciton blocking layer. These materials enhanced maximum quantum efficiency from 8.3% to 13.0% by inserting the exciton blocking layers. |
