Syntheses of metal–organic frameworks with protected phosphonate ligands

Abstract

Protected phosphonate groups were embedded onto isophthalic acid and reacted with zinc ion to synthesize metal–organic frameworks (MOFs). Single-crystal X-ray diffraction measurement revealed the crystal structures of obtained MOFs under various temperatures and solvent conditions. The isopropyl groups were left protected when the complexation reaction was executed at 60 °C, while they were partially deprotected in the sample prepared at 120 °C. When the reaction was carried out at 180 °C, the isopropyl groups were totally deprotected. This result provides us with information on the deprotection reaction in a post-synthetic method for constructing MOFs.
