Figure 1. Customization of FM-MOFs through single substitution. (A) Schematic illustration of constructing FM-MOFs by functional modules with carboxyl connector. (B) Hg²⁺ adsorption kinetics of FM-MOF-1 at the initial concentration of 10 ppm. (C) Ag⁺ adsorption isotherm for FM-MOF-2. The inset shows the linear regression by fitting the experimental data with the Langmuir model. (D) Humidity dependence of the proton conductivities in FM-MOF-3 at room temperature. (E) The effect on the emission spectra of FM-MOF-4 dispersed in DMF upon incremental addition of a TNP solution (1 mM). The inset shows the original fluorescence and the decreased fluorescence upon the addition of TNP solution (1 mM). (F) Contact angle images of FM-MOF-5 and MOF-808.
