Reticular control of interpenetration in a heterogeneity metal-organic framework

Abstract

Metal-organic frameworks (MOFs) are a new generation of crystalline porous materials covering the broad spectrum of research fields due to its high porosity and feasible modification of structure. Owing to large void space, MOF structures tend to be more stable during the growth of crystals leading to interpenetrated frameworks. Control of interpenetrated frameworks in MOFs is not only useful for various kinds of practical application but also provides insight towards understanding the reaction process and catenated behavior in the MOF chemistry. In this research, we sought to investigate and successfully achieve how to reticularly control the interpenetration of PCN-280, a complex MOFs with 2-folds interpenetrated framework containing heterogeneity building blocks, two kinds of polytopic organic linking unit-based carboxylate, to form a new isoreticular single-frame MOF, termed MOF-908 and isoreticular MOF-909. The crystal structure and underlying network of MOF-908 and MOF-909 are proven by X-ray diffraction analysis as well as other related characterizations. Indeed, the mechanism of reticular control of the interpenetration of PCN-280 is studied in detail under the light of density functional theory (DFT) calculation.
