发现了铁电近晶C* 相的溶致类似物，溶致近晶C* 相表现出宏观手性效应，如螺旋基态和极性依赖的电光开关，从而表明存在自发电极化。螺旋性意味着手性指向矢扭转穿过分离手性介晶的相邻层的非手性溶剂层的连通。
A lyotropic analogue of the ferroelectric smectic C* phase has been found. The lyotropic smectic C* phase shows macroscopic chirality effects, such as a helical ground state and polarity‐dependent electrooptic switching, thus indicating the presence of a spontaneous electric polarization. The helicity implies communication of the chiral director twist across the achiral solvent layers separating adjacent layers of the chiral mesogens.
