In this paper, two AIE-active luminogens (Oxa- p TPE and Oxa- m TPE) constructed from tetraphenylethene and oxadiazole units were successfully synthesized and their thermal, optical and electronic properties were investigated. By linking TPE to the oxadiazole core through meta-or para-position, the intramolecular conjugation is effectively controlled. Thanks to the intelligent molecular design and specific AIE feature, when fabricated as emissive layers in non-doped OLEDs, they exhibit blue or deep-blue emission with CIE coordinates of (0.17, 0.23) and (0.15, 0.12), and good efficiencies with η C, max and η P, max up to 1.52 cd A -1 and 0.84 Im W-1, shedding some light on the construction of deep-blue AIE fluorophores.

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 Lmax, ηC,max, ηP,max and ηext,max of 10070 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.
