Synthesis of microporous polymers by Friedel-Crafts reaction of 1-bromoadamantane with aromatic compounds and their surface modification

Adamantane-based microporous polymers were prepared by Friedel-Crafts reaction of 1-bromoadamantane with benzene, biphenyl and terphenyl and then post-functionalized with 4-nitrobenzoyl chloride. At 298 K, the CO2 uptake capacity of the functionalized polymers was increased by 18-25%, owing to the interaction between the nitro group and CO2.
