A novel pillared-layered entangled luminescent metal-organic framework [Zn(bpdc)(BPyTPE)] (1) (BPyTPE = (E)-1,2-diphenyl-1,2-bis(4-(pyridin-4-yl)phenyl)ethene) has been designed and constructed. The solvent-free 1 exhibits strong blue-green emission with an excellent fluorescence quantum yield of 99% and provides a facile and reversible method to sensitively and quantitatively detect trace pesticide of 2,6-dichloro-4-nitroaniline.

By using a tetraphenylethene (TPE)-based ligand, tetrakis[4-(4-carboxyphenyl)phenyl]ethene (H4TCPPE), a porous metal-organic framework [Zn2(TCPPE)] (1) is synthesized, which exhibits strong fluorescence and is capable of gas adsorption and sensing volatile organic compounds.

A tetraphenylethene-based luminescent metal–organic framework efficiently and quantitatively detected trace nitro-containing antibiotics in aqueous media.

A highly luminescent MOF containing tetraphenylethene-based cations has been prepared through in situ encapsulation, which can serve as a fluorescent sensor for selective and sensitive detection of nitrofuran antibiotics in aqueous media.
