Design, synthesize, and characterize porous and thermally stable metal-organic frameworks (MOF-2 through MOF-5) using extended molecular metal carboxylate cluster building blocks.
Synthesized four distinct zinc-based metal-organic frameworks: MOF-2, MOF-3, MOF-4, and MOF-5.
Performed gas sorption and ethanol sorption isotherm measurements on evacuated derivatives at temperatures including 22 °C and 32 °C.
Evaluated structural integrity, free pore volume, and stability using single-crystal diffraction studies and thermal testing.
MOF-2, MOF-3, and MOF-5 display type I gas sorption isotherms, indicating accessible microporous channels with high structural organization.
MOF-4 shows ethanol-driven coordination changes at unsaturated zinc centers from 3- to 4-, 4- to 5-, and 5- to 6-coordination.
The evacuated framework MOF-5 remains stable in air up to 300 °C and exhibits a free pore volume comprising 55% to 60% of the crystal volume.
