Unconventional ionic liquid crystals in which the liquid crystallinity is enabled by halogen-bonded supramolecular anions Cn F2 n+1 -I⋅⋅⋅I⋅⋅⋅I-Cn F2 n+1 are reported. The material system is unique in many ways, demonstrating for the first time 1) ionic, halogen-bonded liquid crystals, and 2) imidazolium-based ionic liquid crystals in which the occurrence of liquid crystallinity is not driven by the alkyl chains of the cation.
报道了一种由卤素键超分子阴离子 Cn F2 n+1 -I⋅⋅⋅I⋅⋅⋅I-Cn F2 n+1 赋予液晶性的非常规离子液晶。该材料体系在许多方面都是独特的，首次展示了 1）离子型、卤素键合液晶，以及 2）基于咪唑鎓的离子液晶，其中液晶相的出现不是由阳离子的烷基链驱动的。
