    • HCl has previously been reported to enhance the synthesis of members of the UiO-66 series when incorporated in large quantities into solvothermal syntheses (see ref. 16 and 20). In our hands, syntheses of Zr-MOFs of ligands with the addition of only one equivalent of HCl did not give reproducible results, particularly in the synthesis of Zr-L6 (UiO-67) with some products showing good crystallinity and others being completely amorphous. This observation correlates with previous work by Behrens, et al., who reported that addition of HCl did not improve their syntheses of UiO-67 (see ref. 6 d)
