Benzene-cored luminogens with multiple triarylvinyl units exhibit aggregation-induced emission. The high solid-state fluorescence quantum yields and high thermal and morphological stabilities of such emitters gave light-emitting diodes with sky-blue to greenish-blue light in high luminance and efficiencies. The emission could be quenched exponentially by picric acid, or selectively by Ru3+, making them highly sensitive (and selective) chemosensors for explosives and metal ions.
