Framework disorder and its effect on the property

What is it about?

In this paper, the effect of framework (pore) disorder on the gas sorption of azole-based isoreticular Cu(II) MOFs with rtl topology and characteristic 1D tubular pore channels is investigated for the first time. A Cu(II) metal–organic framework based on 5-(1H-imidazol-1-yl)isophthalate acid has a crystallographically identifiable disordered framework. It provides a unique example for investigating the effect of pore disorder on gas sorption that can be systematically evaluated. The unique property of the framework is its disordered structure featuring distorted 1D tubular channels and DMF-guest-remediated defects. It exhibits remarkable temperature-dependent hysteretic CO2 sorption up to room temperature, and shows selectivity of CO2 over H2, CH4 and N2 at ambient temperature.

Why is it important?

Metal–organic frameworks with highly ordered porosity have been studied extensively. This paper highlights the importance of framework (pore) disorder in single crystals.
