离子液体前驱体的合成路线

摘要

Because of the advantages of flexibility and self-healing, ionic liquids are becoming intriguing electronic materials for flexible and stretchable electronics. We designed a new kind of light-sensitive ionic liquid with rapid response in the ranges from visible to near-infrared light, which had great potential in the fabrication of optoelectronic devices. A polypyrrole oligomer was introduced to an imidazolium-based ionic liquid and they were covalently linked to each other by alkyl chain of eight carbon atoms. The photothermal conversion of polypyrrole and the electric response of imidazolium were combined to realize the function of light-sensing. Herein, we presented the synthetic route of the precursor 1-[8-(N-Pyrrolyl)octyl]-3-methylimidazolium hexafluophosphate, from commercially available materials pyrrole, 1-methylimidazole, 1,8-dibromooctane and ammonium hexanfluophosphate. NMR spectroscopy was used to confirm the structures.
