2021年3月1日 · The MOF-525 and MOF-545 prepared by the sonochemical route exhibited enhanced hydrolysis of the chemical warfare simulant dimethyl-4-nitrophenyl phosphate (DMNP) and a faster and higher bisphenol-A adsorption than the conventionally prepared MOF samples.

MOF-525 and -535 are composed of Zr6O4(OH)4 cuboctahedral units linked by either porphyrin (MOF-525) or cruciform (MOF-535). Another zirconium-containing unit, Zr6O8(H2O)8, is linked by porphyrin to give the MOF-545 structure. The structure of MOF-525 was obtained by analysis of powder X-ray diffraction data.

The remarkable adsorption capabilities of MOF-525 are attributed to its high specific surface area and the presence of porphine, phenyl, and carboxyl groups. Notably, MOF-525 demonstrates the ability to adsorb single-stranded nucleic acids. Furthermore, it maintains consistent red fluorescence emission when excited.

2024年12月18日 · This study introduces Zr(IV) alkoxides as metal precursors, achieving ultrafast (∼minutes) and high-yield (>90%) synthesis of three well-known Zr-based porphyrinic MOF nanocrystals: MOF-525, PCN-224, and PCN-222, each with distinct topologies.
