Macroscopic chirality of twist-bend nematic phase in bent dimers confirmed by circular dichroism

Many achiral bent molecules and some polymers with such repeat units exhibit a liquid crystal phase transition between a conventional nematic (N), and a second nematic (N x ) with periodically modulated orientation. Theory predicts several possible structures for the N x phase, some of which are chi...
