Membranes surpass established CO2-seperation technologies in terms of overall energy efficiency, but are limited by a trade-off between CO2 permeability and CO2/light-gas-selectvity. Nucleophilic phenolate ions within the membrane open up a highly selective carrier-mediated CO2-transport mechanism, which can be tuned via activating substituent groups at the phenol ring. Phonalte-functionalized membranes exhibit some of the highest CO2/N2 selectivities of all one-polymer-membranes reported to date.     «
