“…The fluorescence quantum yield of the system also increased from 0.0 to 0.02 after PFOA addition (Figure S17 and S18). 80,81 To assess the response time of the U-1 MOF for detecting PFOA, time-dependent experiments were carried out with various concentrations of PFOA solutions (Figure S19). For each concentration of PFOA, the emission intensity (at λ max = 561 nm) of U-1 MOF suspension was measured as a function of time after addition of PFOA.…”

A novel, water-stable, perylene diimide (PDI) based metal−organic framework (MOF), namely, U-1, has been synthesized for selective and sensitive detection of perfluorooctanoic acid (PFOA) in mixed aqueous solutions. The MOF shows highly selective fluorescence turn-on detection via the formation of a PFOA-MOF complex. This PFOA-MOF complex formation was confirmed by various spectroscopic techniques. The detection limit of the MOF for PFOA was found to be 1.68 μM in an aqueous suspension. Upon coating onto cellulose paper, the MOF demonstrated a significantly lower detection limit, down to 3.1 nM, which is mainly due to the concentrative effect of solid phase extraction (SPE). This detection limit is lower than the fluorescence sensors based on MOFs previously reported for PFAS detection. The MOF sensor is regenerable and capable of detecting PFOA in drinking and tap water samples. The PDI-MOF-based sensor reported herein represents a novel approach, relying on fluorescence turn-on response, that has not yet been thoroughly investigated for detecting per-and polyfluoroalkyl substances (PFAS) until now.
