Herein, a novel pillar[5]arene-bridged monomer with two sides functionalized with tetraphenylethylene (TPE) and nitrile group was designed and synthesized. It could form supramolecular aggregates based on the host–guest interaction between TPE and the nitrile group. Due to the restricted intramolecular rotation of the TPE core, the supramolecular aggregates showed prominent aggregation-induced emission.
