On page 1456 , Tai‐Shung Chung and co‐workers show, for the first time, that ultraviolet (UV)‐rearranged polymers of PIM‐1 membranes can be used for H 2 /CO 2 separation with far superior separation performance to others in the literature. It is observed that the original contorted PIM‐1 could be transformed to a close‐to‐planar like rearranged structure after UV radiation. Such membranes could have a H 2 permeability of 452 barrer and a H 2 /CO 2 selectivity of 7.3, which are far superior to recent state‐of‐the‐art values for the separation of H 2 /CO 2 .
