a PXRD patterns of (NH2)x-UiO-66@TDCOF. b FT-IR spectra of (NH2)1.24-UiO-66, (NH2)1.24-UiO-66@DFP, and (NH2)1.24-UiO-66@TDCOF (The red line indicates the imine bond peak). c Core-shell structure model of UiO-66@TDCOF. d SEM image of (NH2)1.24-UiO-66@TDCOF. e HR-TEM image (inset: lattice fringe, d = 0.4 nm) of (NH2)1.24-UiO-66@TDCOF (TDCOF thickness = ~10 nm). f High-angle annular dark-field scanning TEM (HAADF-STEM) and elemental mapping analysis of (NH2)1.24-UiO-66@TDCOF. Each experiment was independently repeated three times to obtain similar results in Fig. 2d-f. Source data are provided as a Source Data file.
