A novel synthetic methodology for preparing chain-extended and cross-linked ionenes using UV irradiation is described. 12,12-Ammonium ionenes were functionalized with either cinnamate or styrenic functionality at the chain ends and were subsequently exposed to UV irradiation. In addition, a novel copolymer (poly(cinDMPC-co-bocDMPC)) was mixed with the cinnamate-functionalized 12,12-ammonium ionene to prepare photo-cross-linked networks. The UV irradiation process was monitored via UV-Vis spectroscopy after each exposure. The chain-extended 12,12-ammonium ionene possessed superior tensile properties compared to the original 12,12-ammonium ionene. Successful cross-linking was confirmed with solubility testing of the thin films in methanol. The results indicated that photo-cross-linked 12,12-ammonium ionenes offer potential in membrane technology applications.
