摘要：

Switching of chirality: A field-induced inversion of the layer chirality has been found in the SmCPA phase of novel bent-core mesogens. Furthermore, a field-induced enhancement of the clearing temperature (transition temperature SmCPA to isotropic) up to 4 K could be observed; this is obviously due to the field-induced alignment of ferroelectric clusters, which exist already in the isotropic liquid. The picture shows a texture of the SmCPA phase with circular domains.
