An azo-linked porous triptycene network as an absorbent for CO2 and iodine uptake

An azo-linked porous organic framework (Azo-Trip) in which triptycene is incorporated as linkage, has been constructed via a facile Zn-induced reductive homocoulping reaction. The Azo-Trip exhibits selective carbon dioxide uptake and excellent iodine uptake in vapour and liquid phase.
