[Abstract]:Ionic liquids are organic molten salts that are liquid at or near room temperature. Ionic liquids are completely anion? Cationic composition, high conductivity, high volatility, excellent thermal stability, chemical stability, wide liquid path and other better chemical and physical properties. It has been widely used in organic synthesis, separation, electrochemistry and macromolecule. It is a good green solvent and electrolyte. Polyionic liquids are a class of ionic polymers formed by polymerization of ionic liquid monomers with anion and cationic repeating units. Polyionic liquids (Pils) have a wide background in the field of polymer science because they have good properties of both polymer and ionic liquids, which can overcome the fluidity of ionic liquids. In addition, supramolecular chemistry based on noncovalent bond interaction has been widely studied in the field of functional materials. In the field of supramolecular materials, functional supramolecular gels have attracted more and more attention in recent years. However, the application of ionic liquids in functional supramolecular gels is rarely reported. In view of the above research status, this paper mainly based on the (poly) ionic liquid supramolecular gel as the research object, using supramolecular interaction to regulate the formation of (poly) ionic liquid based supramolecular gel, and further studied its properties. The research contents and main conclusions are as follows: (1) Supramolecular ionic liquid gel electrolyte was prepared based on host and guest interaction and applied in quasi-solid solar cells. 尾 -CD was used as host, diimidazole ionic liquid (Bis-C12 (mim) Br) was used as guest, dissolved in 1-propyl-3-methyl imidazole (PMII) at room temperature, and self-assembled gel was formed by interaction of host and guest with hydrogen bond between imidazole ionic liquid molecules. When the gel was used in quasi-solid solar cells, the photoconversion efficiency and stability were 4.61%. (2) the CO_2 responsive gel of imidazolium polyionic liquids was prepared by hydrogen bonding. The imidazolium salt polyionic liquid (PIL) gel was prepared by free radical polymerization of imidazole ionic liquid (dimethylamino) ethyl methacrylate (DMAEMA) with polyethylene glycol diacrylate (PEG-DA,Mn 鈮，
