Controlling chirality: A general method to obtain homochiral helical nanofilaments (HNFs) based on a twisted nematic (TN) configuration was developed. By mixing bent-core molecules in the B4 phase with rod-like molecules in the nematic phase, the mixtures show the phase sequence of N–Bx(B4/N). Homochiral HNFs in the Bx phase were obtained from the mixtures when TN cells were cooled. The homochiral HNFs were observed by atomic force microscopy (see picture).
