Tetraphenylethylene Immobilized Metal–Organic Frameworks: Highly Sensitive Fluorescent Sensor for the Detection of Cr2O72– and Nitroaromatic Explosives
Abstract
From the perspective of the chromophore, 1,1,2,2-tetrakis(4-(pyridin-4-yl)phenyl)ethane (TPPE) with the π-electron-rich tetraphenylethylene (TPE) and aggregation induced emission feature is selected as functional ligand to construct the fluorescent metal–organic frameworks. Three luminescent MOFs ( 1 – 3 ) have been successfully synthesized. Through combining 4,4′,4″-nitrilotrisbenzoic acid (H 3 TNB) with electron-donor triphenylamine (TPA), the highly porous pillared-layer compound 1 [Zn 3 (TPPE) 1/2 (TNB) 2 ](4DMA·7H 2 O) was synthesized; interestingly, this MOF sensor film realizes the fast detection for nitrobenzene compounds with a response time of less than 3 min as well as good recyclability. Compound 2 [Zn 7 (TPPE) 2 (SO 4 2– ) 7 ](DMF·H 2 O) exhibits the clear “turn-off” quenching responses for Cr 2 O 7 2– in aqueous phase with high selectivity and sensitivity. Meanwhile, the fluorescent properties of compound 3 [Zn 2 (TPPE) 3/2 (NO 3 – )(OH – )(H 2 O)](DMF·2H 2 O) were also investigated. Thus, these MOF materials could serve as the promising platform for luminescent sensing.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
