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.
多孔 NOTT-202a 对 SO2 具有极高的吸附能力，在 268 K 和 1.0 巴下的吸附量为 13.6 mmol g(-1)（87.0 wt %），这是迄今为止报道的骨架材料中的最高值。NOTT-202a 在 268-283 K 下吸收 SO2 时会发生明显的不可逆骨架相转变，生成 NOTT-202b，由于互穿网络之间形成了强的 π···π 相互作用，NOTT-202b 的稳定性得到增强。
