Bipolar AIE-active luminogens comprised of an oxadiazole core and terminal TPE moieties as a new type of host for doped electroluminescence

For the first time, two bipolar AIE-active luminogens (Oxa-pTPE and Oxa-mTPE) constructed from tetraphenylethene and oxadiazole were utilized as fluorescence host materials in sky-blue doped OLEDs and exhibited high efficiencies with L(max), η(C,max), η(P,max) and η(ext,max) of 10,070 cd m(-2), 9.79...

Zusammenfassung:For the first time, two bipolar AIE-active luminogens (Oxa-pTPE and Oxa-mTPE) constructed from tetraphenylethene and oxadiazole were utilized as fluorescence host materials in sky-blue doped OLEDs and exhibited high efficiencies with L(max), η(C,max), η(P,max) and η(ext,max) of 10,070 cd m(-2), 9.79 cd A(-1), 9.92 Im W(-1) and 5.0%, respectively, broadening the scope for the utilization of AIE materials in the optoelectronic field.
