| Abstract |
An amino-functionalized Zn(II)-MOF (1) was successfully synthesized, structurally characterized, and further utilized as dual-responsive fluorescent sensor for the detection of 2,4,6-trinitrophenol (TNP), one of explosive chemical. 1 exhibits non-porous 5-fold interpenetrated 3D framework decorating with the Lewis basic amino group for recognizing the guest molecule. 1 presents not only excellent water and thermal stability but also tolerance to acidic and basic media over an extensive pH range of 2-12. This ultrastable MOF can acts as fluorescent sensor for TNP sensing with the unprecedented solvent-dependent fluorescent response. Significantly, 1 not only displays high sensitive fluorescent enhancement upon TNP binding in ethanol but also exhibits fluorescent quenching toward TNP in water with very low limits of detection of 4.47nM and 0.32μM in ethanol and water, respectively. Importantly, the fluorogenic changes of 1 induced by TNP can be easily detected by naked eyes and it can be simply and rapidly regenerated, displaying excellent recyclability. The sensing mechanisms were also discussed in detailed. The strategy explained in this work could pave the way for development fluorescent sensors for hazardous chemicals detection, which is relevant in environmental protection, human health and social security.
Keywords: Ultrasatable MOF, Dual-responsive fluorescent sensor, 2,4,6-trinitrophenol
