Irreversible Network Transformation in a Dynamic Porous Host Catalyzed by Sulfur Dioxide

Porous NOTT-202a shows exceptionally high uptake of SO2, 13.6 mmol g–1 (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 268–283 K to give NOTT-202b whi...

Description
Summary:Porous NOTT-202a shows exceptionally high uptake of SO2, 13.6 mmol g–1 (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 268–283 K to give NOTT-202b which has enhanced stability due to the formation of strong π···π interactions between interpenetrated networks.
