Novel Carbazole/Fluorene Hybrids:  Host Materials for Blue Phosphorescent OLEDs

A series of carbazole/fluorene (CBZm-Fn) hybrids were effectively synthesized through Friedel−Crafts-type substitution of the carbazole rings. These compounds were thermally and morphologically stable host materials for OLED applications. Efficient blue phosphorescent OLEDs were obtained when employ...

Zusammenfassung:A series of carbazole/fluorene (CBZm-Fn) hybrids were effectively synthesized through Friedel−Crafts-type substitution of the carbazole rings. These compounds were thermally and morphologically stable host materials for OLED applications. Efficient blue phosphorescent OLEDs were obtained when employing CBZ1-F2 as the host and FIrpic as the guest.
