Gas
storage/separation is a typical application of porous materials such
as metal organic frameworks (MOFs). The adsorption/separation behavior
results from the host–guest and/or guest–guest interaction
and equilibration (host, porous material; guest, adsorbates). Although
the driving forces for gas adsorption have been investigated, a detailed
picture of interactions between gas molecules and MOFs has not clearly
emerged. Herein, a new cobalt microporous MOF [Co(tipb)(adc)](DMF)3(H2O)1.5, which possesses a rare self-interpenetrated gra topology, has been prepared with both tipb and H2adc ligands (tipb = 1,3,5-tris(p-imidazolylphenyl)benzene,
adc = 9,10-anthracenedicarboxylate). This MOF shows high stability
and exceptional selective adsorption of CO2 over N2, O2, and CH4. In particular, a theoretical
assumption of a “regional dynamic electric field effect”
is proposed to clarify the selective adsorption. Moreover, we suggest
that the proposed effect may be one of the most important factors
impacting gas separation and storage in porous materials.
