Novel imidazolium salts of formula (I) are described in which R is a C1-C14 alkyl group, optionally substituted by one or more fluorine atoms, or a C2-C18 alkoxyalkyl group, R' is an alkyl group containing at least 8 carbon atoms, at least 6 of which are partially or entirely fluorinated, R" is hydrogen or C1-C3 alkyl, Z is an organic or inorganic anion, and Q is further defined. The compounds of formula (I) are liquid crystals over a wide temperature range, and are characterised by high conductivity, hydrophobicity and stability. These properties made them ideally suitable for use in devices based on electrochemical reactions, such as solar cells, fuel cells, electrochemical sensors, lithium batteries and capacitors, etc.
                            描述了式 (I) 的新型
咪唑鎓盐,其中 R 是可选被一个或多个
氟原子取代的 C1-C14 烷基或 C2-C18 烷氧基烷基,R'是含有至少 8 个碳原子的烷基,其中至少 6 个部分或全部
氟化,R "是氢或 C1-C3 烷基,Z 是有机或无机阴离子,Q 是进一步定义的。式(I)化合物在很宽的温度范围内都是液晶,具有高导电性、疏
水性和稳定性。这些特性使它们非常适合用于基于电
化学反应的设备,如太阳能电池、燃料电池、电
化学传感器、
