FLEXIBLE IONIC BUILDING BLOCKS WITH HIGH IONIC CONDUCTIVITY AND ALKALINE STABILITY FOR USE IN STRUCTURED ORGANIC FILM (SOF) CONTAINING ANION EXCHANGE MEMBRANES (AEMs)

Abstract

A structured organic film (SOF) includes a plurality of segments, and a plurality of linkers, where at least one of the plurality of linkers connects at least one of the plurality of segments. The film also includes where at least one or more of the plurality of segments may include an ionic species or a nonionic species. The structured organic film (SOF) can include a piperidinium-based quaternary ammonium segment. The piperidinium-based quaternary ammonium compound may include N-hydroxyethylmethyl-4-piperidiniummethanol (NHM4PiP). At least one of the plurality of segments may include a pyridinium-based quaternary ammonium compound. The pyridinium-based quaternary ammonium compound may include N-hydroxyethyl-4-pyridiniummethanol (NH4MPy). Free-standing structured organic films can be folded without cracking at a fold line and are flexible and water-swellable and stable without tearing during exposure to water, and flexible and stable without tearing subsequent to water exposure and drying.
