A Two-Fold Interpenetrating Porous Metal–Organic Framework with a Large Solvent-Accessible Volume: Gas Sorption and Luminescent Properties

A luminescent
porous metal–organic framework based on π-electron-rich
tricarboxylate has been solvothermally prepared and characterized
by Fourier transform infrared spectroscopy, thermogravimetric analysis,
elemental analyses, and single-crystal X-ray diffraction analysis.
This compound is a 2-fold interpenetrating framework with a large
solvent-accessible volume and exhibits gas sorption behaviors for
N2, H2, and CO2 gases and relatively
strong interactions between CO2 and the framework. Furthermore,
it also shows interesting guest-responsive luminescent changes toward
different solvent molecules.
