Ionic polymers that contain ammonium and phosphonium units have demonstrated outstanding ability to form supramolecularly organized films via facile layer-by-layer deposition as well as antibacterial properties. This Creative Inquiry project involved the synthesis of a series of phosphonium polyelectrolytes via polymerization of a variety of diphosphines with bis(bromomethyl)arene comonomers, leading to the cationic polyelectrolytes of interest. The spacer between charged units was varied to include flexible, rigid, and electroactive moieties. The influence of polymer structure on film formation, supramolecular assembly and antibacterial properties are discussed in this contribution.
