(a) AFM-topography image of HKUST-1 structures, prepared by spray coating after grafting squared areas of MPA into the DT matrix thiol. (b) Cross section along the white line of (a). (c) FT-IR imaging of the wavenumber region between 1510 cm⁻¹ and 1780 cm⁻¹. (d) FT-IR spectra representing the area inside the squares (red line in (d) corresponding to red dot in (c)) and outside of the structures (blue line in (d), according to the blue dot in (c)).
