Normalized concentrations of linkers (see Exp. Details) in the liquid state of SALE as functions of time, as calculated from liquid-state 1H NMR spectra. Reactions were performed in DMSO-d6 at 57 °C. Dots represent the spread of the normalized concentrations calculated from the mass of MOF present and the uncertainty of the balance (0.1 mg). For clarity, only every 12th data point is shown in the in situ data series.
