Give me more fluorines: introduction of fluorine in the structure of Covalent Triazine Frameworks can improve their CO2 adsorption. Materials with optimal fluorine content and narrow nanopore distribution are promising CO2 scavengers.

triazine units, fluorine, and ether groups, these carbon molecular sieve membranes obtained after pyrolysis exhibit intrinsic ultra-micropores, high surface areas and excellent thermalstability under air. Excellent CO2 permeability and CO2 to N2 selectivity surpassing the Robeson upper bound are achieved. Our general design and synthesis protocol allow an easy access to fluorinated porous membranes, thus
