Porous NOTT-202a shows exceptionally high uptake of SO₂, 13.6 mmol g^鈥? (87.0 wt %) at 268 K and 1.0 bar, representing the highest value reported to date for a framework material. NOTT-202a undergoes a distinct irreversible framework phase transition upon SO₂ uptake at 268鈥?83 K to give NOTT-202b which has enhanced stability due to the formation of strong 蟺路路路蟺 interactions between interpenetrated networks.
