Abstract

original image

A separation story! A microporous metal–organic framework (UTSA-34) of non-interpenetrated binodal (4,6)-connected ybh network with interconnected cages of about 12.8 Å has been realised to exhibit highly selective separation of C2 hydrocarbons from methane with a separation capacity of 3.0 mol kg−1 and selectivity of 35 at room temperature (see figure).
