Regioisomer effects of dibenzofuran-based bipolar host materials on yellow phosphorescent OLED device performance
Nam Hee Cho, Jun Yeob Lee, Oh Young Kim, Seok‐Ho Hwang
Abstract
Four regioisomers were synthesized for use as bipolar host materials for phosphorescent organic light-emitting diodes (PhOLEDs) by classic cross-coupling reactions using cyanofluorene and fused dibenzofuran and were readily purified.
