Figure 3

(a) Fluorescence spectra of Hf-MOF (red, solid), Zr-MOF (blue, solid), and H2L ligand (insoluble particle, black, solid) suspensions in water (0.04 mM L) excited at a wavelength of 368.8 nm. The corresponding excitation spectra monitored at 469 nm are shown in dashed lines. (b) Time-dependent fluorescence decay traces of Hf-MOF (red), Zr-MOF (blue), and H2L ligand (black) suspensions in water excited at 368.8 nm and monitored at 469 nm, together with instrument response function (IRF, gray).
