A Salicylbisimine Cage Compound with High Surface Area and Selective CO2/CH4 Adsorption

Preference for polar adsorbates: The crystalline porous organic cage compound shown has an exceptional high surface area (1566 m2 g−1) and selective gas uptake. The compound preferably adsorbs CO2 (9.4 wt %) over methane (0.98 wt %). Detailed facts of importance to specialist readers are published as ”Supporting Information”.
