A chiral molecule absorbs preferentially right- or left-handed circularly polarized light in a circular dichroism (CD) measurement. Usually, the chirality of individual molecules is regarded as the origin of the CD signals. However, recently, several reports have suggested that the vortex flow of a solution of an achiral molecule gives rise to a CD signal, which is dependent on the stirring direction. This article introduces types of molecular architecture and material designs that show stir-induced chirality. We also discuss the effects of the molecular structure and alignment in vortex flows on this phenomena, reviewing the related issues.
