Selective Proton Transport
In article number 2215109, Tongwen Xu, Liang Ge, Xingya Li, and co‐workers report a series of dibenzo‐18‐crown‐6 functionalized sulfonated poly(biphenyl alkylene) membranes. The membranes possess synergistic hydrophilic networks induced by bi‐functional sites (crown ether and sulfonic‐acid group), increasing selective proton transport, and providing efficient acid recovery...
Acid recycling via cation exchange membranes (CEMs) has attracted considerable attention from traditional industries and advanced manufacturing because of the economic and environmental advantages. However, current polymeric CEMs merely have constant ion channels by the fixed groups in the matrix and lack the synergy of bi‐functional sites. Herein, a series of dibenzo‐18‐crown‐6 (DB18C6) functionalized...
