Two trisdibenzofuran-derived compounds, 4,2′:8′,4′′-terdibenzo[b,d]furan (TDBF) and [4,2′:8′,4′′-terdibenzo[b,d]furan]-6,6′′-dicarbonitrile (CNTDBF), were developed and investigated as electron transport type exciton blocking materials of blue phosphorescent organic light-emitting diodes (PhOLEDs).
