Headed for a membrane : Continuous, polycrystalline ZIF‐90 membranes (picture, left) can be grown at 65 °C from methanolic precursor solutions on nanocrystal‐seeded surfaces of poly(amide–imide) macroporous hollow fibers (right). The ZIF‐90 membranes exhibit good separation properties for linear over cyclic hydrocarbons, as well as gas permeation selectivities higher than Knudsen values.
