Abstract
A structured organic film (SOF) is disclosed including a plurality of segments, a plurality of linkers, and a plurality of ionic capping segments, where at least one or more ionic capping segments may include imidazolium. Implementations of the structured organic film (SOF) include where a concentration of ionic capping segments in the SOF is from about 0.1 to about 5.0 molar equivalents of ionic capping segments as compared to a concentration of nonionic segments in the SOF. A thickness of the SOF is from about 100 nm to about 500 μm. At least one of the plurality of ionic capping segments may include n-hydroxyethyl-1,2,4,5-tetramethylimidazolium (NETMImBr). At least one of the plurality of ionic capping segments may include n-hydroxypropyl-1,2,4,5-tetramethylimidazolium (NPTMImBr). An ion-exchange membrane may include the structured organic film (SOF).
