Short summary
Missing cluster defects in UiO-66 MOFs can be precisely controlled by adjusting the concentration and acidity of monocarboxylic acid modulators during synthesis, thereby tuning the material's porosity and composition.

Key points
- Missing cluster defects are the predominant defect in UiO-66 synthesized with monocarboxylic acid modulators.
- The concentration of missing cluster defects can be tuned by changing the concentration of the modulator.
- The acidity of the modulator also influences the concentration of missing cluster defects.
- Tuning defect concentration directly alters the porosity and composition of the UiO-66 material.

Abstract
Presented in this paper is a deep investigation into the defect chemistry of UiO-66 when synthesized in the presence of monocarboxylic acid modulators under the most commonly employed conditions. We unequivocally demonstrate that missing cluster defects are the predominant defect and that their concentration (and thus the porosity and composition of the material) can be tuned to a remarkable extent by altering the concentration and/or acidity of the modulator. Finally, we attempt to rationalize these observations by speculating on the underlying solution chemistry.
