Carbon monoxide (CO) produced in many large-scale industrial oxidation processes is difficult to separate from nitrogen (N2), and afterward, CO further oxidized carbon dioxide. Here, we report a soft nanoporous crystalline material that selectively adsorbs with adaptable pores, present crystallographic evidence molecules can coordinate copper(II) ions. The unprecedented high selectivity was achieved by the synergetic effect of local interaction between accessible metal sites global transformation framework. This transformable realized separation mixtures N2, gas most competitive CO. dynamic efficient molecular trapping releasing system reminiscent sophisticated biological systems such as heme proteins.
