Multifunctional properties of chiral molecules arise from the coexistence of mirror-symmetry-induced stereoisomers and optical rotation characteristics in one material. One of these complex phenomena in these molecules is chiral ferroelectricity, providing the coupling between polarized light and the spatial asymmetry induced dipole moment. Herein we describe the chiral polarization and electroresistance in molecular ferroelectric (R)-(−)-3-hydroxyquinuclidinium chloride thin films with a Curie temperature of 340 K. The high transmittance of chiral ferroelectrics is coupled with polarized light for a linear electro-optic effect, which exhibits angle-dependent optical behaviors. The polarization-controlled conductance imposes a large on/off ratio (∼26.6) of electroresistive switching in molecular ferroelectrics with superior antifatigue endurance.

具有极化光学效应和电阻转换的手性分子铁电体
手性分子的多功能性质源于一种材料中镜像对称诱导的立体异构体和旋光特性的共存。这些分子中的这些复杂现象之一是手性铁电，提供了偏振光与空间不对称感应偶极矩之间的耦合。在此我们描述分子铁电体（R）-（-）-3-羟基喹啉氯化物薄膜，居里温度为340K。手性铁电体的高透射率与偏振光耦合以产生线性电光效应，表现出随角度变化的光学行为。极化控制的电导在具有出色的抗疲劳强度的分子铁电体中施加大的开/关比（〜26.6）的电阻开关。
