| Summary: | <p> The synthesis of zirconium metal–organic frameworks (Zr MOFs) modulated by various amino acids, including <span class="smallCaps">l</span>-proline, glycine, and <span class="smallCaps">l</span>-phenylalanine, is shown to be a straightforward approach toward functional-group incorporation and particle-size control. High yields in Zr-MOF synthesis are achieved by employing 5 equivalents of the modulator at 120 °C. At lower temperatures, the method provides a series of Zr MOFs with increased particle size, including many suitable for single-crystal X-ray diffraction studies. Furthermore, amino acid modulators can be incorporated at defect sites in Zr MOFs with an amino acid/ligand ratio of up to 1:1, depending on the ligand structure and reaction conditions. The MOFs obtained through amino acid modulation exhibit an improved CO<sub><font size="2">2</font></sub>-capture capacity relative to nonfunctionalized materials.</p> |
