Hydroxy-functionalized hyper-cross-linked ultra-microporous organic polymers for selective CO₂ capture at room temperature.

ABSTRACT: Two hydroxy-functionalized hyper-cross-linked ultra-microporous compounds have been synthesized by Friedel-Crafts alkylation reaction and characterised with different spectroscopic techniques. Both compounds exhibit an efficient carbon dioxide uptake over other gases like N₂, H₂ and O₂ at room temperature. A high isosteric heat of adsorption (Q_st) has been obtained for both materials because of strong interactions between polar -OH groups and CO₂ molecules.
