Kinetic hysteresis in gas adsorption behavior for a rigid MOF arising from zig-zag channel structures

A new porous MOF, Zn(TBC)(2)center dot{guest}, is synthesized and studied by the single crystallography, N-2 isothermal adsorption and GC separation of CO2 from air. This MOF shows large hysteresis on N-2 adsorption at 77 K up to a P/P-o of 0.9, which arises from the unique zig-zag channel structures of the framework. The MOF shows promising separation ability for CO2 from air.
