Abstract
Metal-organic frameworks (MOFs) usually exist in the state of powder or crystal. When they are exposed to hydrophilic solvents, their structure will change and become unstable. Therefore, it is a challenge to construct MOF materials with tunable mechanical properties. Herein, we report in-situ growth lanthanide metal-organic framework (LnMOF) in sodium alginate (SA) and polyvinyl alcohol (PVA) hydrogel matrix. The prepared composite hydrogel not only displays characteristic lanthanide narrow-band emission under ultraviolet light, but also demonstrates excellent mechanical properties. The addition of LnMOF significantly enhances the compressive strength of the hydrogel (from 0.75 to 7.32 MPa). Furthermore, the composite hydrogel shows highly selective recognition of glutaraldehyde and gaseous formaldehyde at room temperature. The detection limits (LOD) of SP-EuMOF for glutaraldehyde and formaldehyde are 0.27 and 0.22 ppm, respectively. Based on these results, the LnMOF composite hydrogel is deemed to have significant potential as a fluorescent sensor for both glutaraldehyde and formaldehyde detection.
