Figure 3. Full conversion process among FM-MOFs: (A and B) scheme illustration of mutual transformation among FM-MOFs and the associated pore structures of FM-MOF-2, FM-MOF-7, and FM-MOF-9; (C) the conversion process characterized by 1H NMR spectra; and (D) the conversion rate from FM-MOF-9 to FM-MOF-7 with the increase of time.
