Fig. 6. The “Seesaw” relationship between nanocrystal sizes and added equivalents of acidic ligands. Nanocrystal sizes increase with higher ratios of metal-to-linker local concentrations (A) particles reach a minimum size α at critical values of acidic ligand ε and minimum relative ratios local metal ion-to-ligand concentrations β and relative ratios diffusion and metal–ligand complexation ratios σ. (B) MIL-125-NH2 and UiO-66 exhibit the full seesaw relationship curve in trends between particle sizes and equivalents of p-toluic acid.66.
