Abstract
An octa-nuclear zinc (Zn8) cluster-based two-fold interpenetrated metal-organic framework (MOF) of [(CH3)2NH2]2[Zn8O3(FDC)6]·7DMF (denoted as Zn8-as; H2FDC = 9H-fluorene-2,7-dicarboxylic acid; DMF = N,N-dimethylformamide) was synthesized by the reaction of a hard base of a curved dicarboxylate ligand (H2FDC) with the borderline acid of Zn(II) under solvothermal conditions. Zn8-as shows significant crystal volume shrinkage upon heating, yielding a solvate-free framework of [(CH3)2NH2]2[Zn8O3(FDC)6] (Zn8-de). Zn8-de displays gated adsorption for C2H2 and type-I adsorption for CO2, attributed to the framework flexibility and the different interactions between the gas molecules and the host framework.

Augmenting the Carbon Dioxide Uptake and Selectivity of Metal-Organic Frameworks by Metal Substitution: Molecular Simulations of LMOF-202. ACS OMEGA 2020; 5:17193-17198.

Abstract
Metal organic frameworks (MOFs) are promising porous materials for the adsorption of CO2. Here, we report the study of a luminescent MOF (LMOF), called LMOF-202. We have employed Grand Canonical Monte Carlo (GCMC) simulations to understand and explain the adsorption phenomena inside LMOF-202, and based on the phenomena happening at the molecular level, we have varied the metal ions in LMOF-202 to increase the CO2 affinity and selectivity of the material. We show that the CO2 adsorption capacity and selectivity can be increased by approximately 1.5 times at 1 bar and 298 K by changing the metal ion from Zn to Ba. We also report the feasibility of using this material to capture CO2 from flue gas under realistic conditions (1 bar and 298 K). This work shows that LMOF-202 merits further consideration as a carbon capture adsorbent.
