多孔NOTT-202a在268 K和1.0 bar下表现出异常高的SO2吸收量，为13.6 mmol g(-1) (87.0 wt %)，是迄今为止报道的框架材料的最高值。NOTT-202a在268-283 K的SO2吸收过程中经历了明显的不可逆框架相变，从而使NOTT-202b由于形成强pi而增强了稳定性。相互渗透的网络之间的PI交互。
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 pi...pi interactions between interpenetrated networks.
