The intriguing phenomenon of aggregation-induced emission (AIE), first reported by Tang et al. in 2001, has been demonstrated as an e?ective way to tackle the notorious aggregation-caused quenching (ACQ) effect and aroused a new research topic of AIE materials as promising candidates for OLEDs and bioprobes. Among the archetypal AIE molecules, tetraphenylethene (TPE) enjoys the advantages of facile synthesis and outstanding AIE effect. Although lots of TPE-based luminogens with excellent electroluminescence performance have been developed, blue AIE luminogens are still scarce for the intrinsic extension of intramolecular conjugation. In this paper, we mainly review our recent work on the construction of blue- or deep-blue TPE-based solid emitters for OLEDs. The facile synthetic approaches and the device performance of the resulting materials are well demonstrated.
