Abstract:
A novel TPE-based expanded oxacalixarene with typical aggregation-induced emission properties was synthesized by the SNAr reaction of dihydroxytetraphenylethylene with 2,6-dichloropyrazine. The conformation of the oxacalixarene is adjusted by the encapsulated guests (benzene or THF), which results in different supramolecular grid structures in the solid state.
