a PXRD patterns (blue line refers to simulated PXRD pattern). The defects in Cu2(L)-e result in broadening of peaks due to poorer crystallinity of the material. b Micrograph (top) and CFM image (bottom) of Cu2(L)-t. The fluorescence (shown in red colour) indicates the presence of crystal defects determined by the oligomerisation of furfuryl alcohol. c Micrograph (top) and CFM image (bottom) of Cu2(L)-e. d Selected FTIR spectra (full spectra are shown in Supplementary Information). e TGA curves. f X-band EPR spectra at room temperature. g Q-band EPR spectra at room temperature. h Second integrals from simulated Q-band EPR spectra for Cu2(L)-t. i Second integrals from simulated Q-band EPR spectra for Cu2(L)-e. j N2 adsorption/desorption isotherms at 77 K. k Micropore size distribution. l Mesopore size distribution. m Adsorption isotherms for CO2 at 298 K (desorption data are shown in Supplementary Information). Data for HKUST-1-e are shown in Supplementary Information. The scale bars of b and c are 20 μm.
