Structured organic films containing n-cyclic quaternary ammonium having cationic charge functionality and methods thereof

Abstract

A structured organic film (SOF) is disclosed. The structured organic film also includes a plurality of segments, a plurality of linkers, and a plurality of ionic capping segments, where at least one or more of the ionic capping segments may include a piperidinium group. Implementations of the structured organic film (SOF) may include where the piperidinium group is a bicyclic piperidinium group. The piperidinium group can be an n-cyclic quaternary ammonium. A total concentration of ionic segments in the SOF is from about 0.1 to about 5.0 molar equivalents based on a total concentration of segments in the SOF. The piperidinium group can be 3-methanol-6-azoniaspiro[5.5]undecane (MeASU). The structured organic film (SOF) has an ion exchange capacity (IEC) of from about 0.25 meq/g to about 5.00 meq/g. An ion-exchange membrane may include the structured organic film (SOF).
