Abstract

Abstract: A multifunctional AIE‐active molecule, CzPySiTPE, in which carbazole (Cz) and pyridine (Py) were attached to tetraphenylsilane to facilitate carrier injection has been designed and synthesized. Tetraphenylethene (TPE) was adopted to maintain efficient blue emission. Blue electroluminescent (EL) emission of CzPySiTPE was obtained with CIE coordinates of (0.16, 0.17) and an external quantum efficiency of 1.12 %. Abstract : A multifunctional AIE‐active molecule has been synthesized to combine the merits of carbazole, pyridine, and tetraphenylethene moieties. This molecule exhibits blue emission with CIE coordinates of (0.16, 0.17) and an external quantum efficiency of 1.12 % (see figure; AIE=aggregation induced emission).
