A 1-propyl-3-methylimidazolium iodide based supramolecular ionic liquid gel was prepared through the host-guest interactions between a host of β-cyclodextrin and a room temperature ionic liquid type guest, 1-ethyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)imide, which contains bis(trifluoromethylsulfonyl)imide as the guest group. The gel-to-sol phase transition temperature of the prepared supramolecular ionic liquid gel could be tuned by the ratio of host to guest. The synthesized supramolecular ionic liquid gel was further applied in quasi-solid-state electrolyte dye-sensitized solar cells, which showed a power conversion efficiency of 4.79% under the simulated air mass 1.5 solar spectrum illumination at 100 mW cm(-2) and excellent long-term stability.
通过主体β-环糊精与室温离子液体型客体1-乙基-3-甲基咪唑双（（三氟甲基）磺酰）亚胺之间的主客体相互作用，制备了一种基于1-丙基-3-甲基咪唑碘化物的超分子离子液体凝胶，该客体含有双（三氟甲基磺酰）亚胺作为客体基团。所制备的超分子离子液体凝胶的凝胶-溶胶相变温度可通过主体与客体的比例进行调节。合成的超分子离子液体凝胶进一步应用于准固态电解质染料敏化太阳能电池，在100 mW cm(-2)的模拟空气质量1.5太阳光谱光照下，其功率转换效率为4.79%，并具有优异的长期稳定性。
