Abstract:
An unprecedented meso-decorated pillar[5]arene derivative, EtP5A-DPE, embedded with a TPE unit was prepared and structurally characterized. In the crystal, the incubation of the guest 1,4-dicyanobutane molecule inside the tetraphenylethene-embedded pillar scaffold induces a significant change in the molecular conformation, shutting down the AIE emission of this compound.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
