Mg-MOF-74(S) (1640 m 2 g −1 BET surface area) displayed similar textural properties to those of a high-quality MOF sample synthesized in 24 h by the solvothermal method (Mg-MOF-74(C), 1525 m 2 g −1). However, mesopores were formed, probably due to the competitive binding of TEA to Mg 2+ ions, and the average particle size of the former (ca. 0.6 μm) was significantly smaller than that of Zn‐MOF‐74‐ d,l ‐Pro (MeOH or DMF): The activated Zn‐MOF‐74 (0.029 g; 0.089 mmol; 1.0 equiv.) and d ‐ or l ‐Pro (0.010 g; 0.089 mmol; 1.0 equiv.) were added to a glass vial containing 2.5 mL methanol or DMF, resulting in a yellow‐white nonhomogeneous mixture.
