Nanodomain Control in Carbon Molecular Sieve Membranes via Nanomaterial Footprinting

Carbon Molecular Sieves In article number 2300162, Gyorgy Szekely and co-workers report the fabrication of composite carbon molecular sieve membranes by incorporating sphere-shaped C60(OH) and ellipsoid-shaped C70(OH) fullerenols into an intrinsically microporous polyimide and characterize the chemical footprints of the pyrolyzed membranes and their chemical inhomogeneity at the nanodomain level. The membranes demonstrate excellent stability and pharmaceutical and dye separation performance in organic media.
